Circumstances:
The twin engine aircraft, with a pilot and a flight nurse on board, was being operated by Skymaster Air Services under the instrument flight rules (IFR) on a flight from Bankstown Airport, New South Wales (NSW) to Archerfield Airport, Queensland. The aircraft was being positioned to Archerfield for a medical patient transfer flight from Archerfield to Albury, NSW. The aircraft departed Bankstown at 0740 Eastern Standard Time. At 0752, the pilot reported to air traffic control (ATC) that he was turning the aircraft around as he was having ‘a few problems. At about 0806, the aircraft collided with a powerline support pole located on the eastern side of the intersection of Sackville Street and Canley Vale Road, Canley Vale, NSW. The pilot and flight nurse sustained fatal injuries and the aircraft was destroyed by impact damage and a post-impact fire.
Probable cause:
Contributing safety factors:
• While the aircraft was climbing to 9,000 feet the right engine sustained a power problem and the pilot subsequently shut down that engine.
• Following the shutdown of the right engine, the aircraft's descent profile was not optimized for one engine inoperative flight.
• The pilot conducted a descent towards Bankstown Airport that was consistent with a normal arrival profile without first verifying that the aircraft was capable of achieving adequate performance with one engine inoperative.
• Following the engine problem, the aircraft's flightpath and the pilot’s communication with air traffic control indicated that the pilot's situation awareness was less than optimal.
• The aircraft collided with a powerline support pole on the eastern side of the intersection of Sackville Street and Canley Vale Road, Canley Vale, about 6 km north-west of Bankstown Airport.
Other safety factors:
• The pilot did not broadcast a PAN following the engine shutdown and did not provide air traffic control with further information about the nature of the problem in order for the controller to positively establish the severity of the situation.
• Section 4 of Civil Aviation Advisory Publication (CAAP) 5.23-2(0), Multi-engine Aeroplane Operations and Training of July 2007 did not contain sufficient guidance material to support the flight standard in Appendix A subsection 1.2 of the CAAP relating to Engine Failure in the Cruise. [Minor safety issue]
Other key finding:
• Given the pilot’s extensive experience and testing in the PA-31 aircraft type, and subsequent endorsement training on a high performance turboprop multi-engine aircraft since the issue by CASA in 2008 of a safety alert in respect of the pilot’s PA-31 endorsement, it was unlikely that any deficiencies in that endorsement training contributed to the accident.

Circumstances:
The aircraft was completing an ambulance flight from Palm Beach to Rio de Janeiro with intermediate stops in Aguadilla and Manaus, carrying one patient, a medical team and two pilots. During the takeoff roll from 10 at Manaus-Eduardo Gomes Airport, just before V1 speed, the crew heard a loud noise coming from the right side of the airplane. In the mean time, the aircraft started to deviate to the right. The captain decided to abandon the takeoff procedure and initiated a braking maneuver. Unable to stop within the remaining distance, the aircraft overran and came to rest 400 metres past the runway end. All six occupants escaped uninjured while the aircraft was damage beyond repair.
Probable cause:
The following findings were identified:
- The external tyre on the right main gear deflated during the takeoff roll,
- The crew retarded the power levers and deployed the spoilers,
- The crew did not use the parachute, judging the relative low speed and thinking this was an optional equipment,
- Technical analysis on the right main gear revealed that the six bolts on the external wheel torque were approximately 90% lower than foreseen, which may contributed to the tyre deflection.

Circumstances:
The aircraft took off at 0041 hrs from Hanover (EDDV) for a positioning flight to Munich (EDDM) with a crew of two pilots. The intention was to make a subsequent air ambulance flight from Munich to Kiel. During the climb the crew received the instruction for a direct flight to Munich and the clearance for a climb to Flight Level (FL) 230. The radar data showed that the aircraft turned south-east and climbed to FL230 after take-off. At 0123:45 hrs the crew made radio contact with Munich Radar. About five minutes later, the controller advised the crew that both runways were closed for snow removal, but that the southern runway would re-open in about 25-30 minutes. In response, the crew advised they would reduce the speed somewhat. The crew stated that the temperature in flight altitude had been -40 °C. At 0133:58 hrs the controller issued descent clearance to FL110. According to crew statements in this phase there were problems with the left engine. A system check indicated that the engine’s Interstage Turbine Temperature (ITT) had exceeded 900°C and the torque had reduced to zero. The crew then first worked through the memory items before "beginning with the engine failure checklist". In the presence of the BFU the crew gave their reasons for the shut-off of the engine as being the fast increase of the ITT and the decrease of the torque to zero. The crew could not give any other engine parameters like Ng per cent RPM, propeller RPM, fuel flow, oil pressure or oil temperature. The co-pilot reported via radio: "… we request to maintain FL150 … we have engine failure on the left side, call you back." At that time, the radar data showed the aircraft at FL214. As the controller asked at 0138:15 hrs if a frequency change to approach control were possible, the co-pilot answered: "... give us a minute, please, and then we report back, until we have everything secured ..." At 0143:22 hrs the co-pilot advised the controller that the engine had been "secured" and a frequency change was now possible. The crew subsequently reported that, three to five minutes later there had been brief, strong vibrations in the right engine. The crew could not state which actions they had carried out after the descent clearance and during shut-off and securing of the left engine. Both pilots stated that there was no attempt to re-start the left engine. After changing frequency to Munich Approach Control the crew was advised that runway 26L was available. The co-pilot declared emergency at 0143:48 hrs, about 25 NM away from the airport of destination, mentioning again the failure of the left engine. The controller responded by asking the crew what assistance they would require, and asked if a ten-mile approach would be acceptable. This was affirmed. At 0149:28 hrs the controller gave clearance for an ILS approach to runway 26L. At that time the radar data showed the airplane in FL78 flying with a ground speed of 210 kt to the south-east. The aircraft turned right towards the final approach and at 0151:53 hrs it reached the extended runway centre line about 17 NM prior to the runway threshold in 5,400 ft AMSL with a ground speed of 120 kt. At 0154:12 hrs the controller said: "… observe you a quarter mile south of the centre line." According to the radar data the aircraft was in 5,000 ft AMSL with a ground speed of 90 kt at that time. The co-pilot answered: "Ja, we are intercepting…". Twenty seconds later the controller gave clearance to land on runway 26L. Up until about 0157:30 hrs the ground speed varied between 80 and 90 kt. From 0157:43 hrs on, within about 80 seconds, the speed increased from 100 kt to 120 kt. Thereby, the airplane had come within 5.5 NM of the threshold of runway 26L. Up until 0200:53 hrs the airplane flew with a ground speed of 100 - 110 kt. At 0201:32 hrs ground speed decreased to 80 kt. At that time, the airplane was in 1,900 ft AMSL and about 1.5 NM away from the threshold. Up until the last radar recording at 0202:27 hrs the ground speed remained at 80 kt. The crew stated the approach was flown with Blue Line Speed. During the final approach the aircraft veered slightly to the left and tended to sink below the glidepath. Approximately 3 NM from the threshold the approach lights had become visible and the flaps and the landing gear were extended. Then the airplane veered to the left and sank below the glidepath. The co-pilot stated a decision for a go-around was made. When an attempt was made to increase power from the right engine, no additional power was available. The aircraft had lost speed and to counteract it the elevator control horn was pushed. Prior to the landing, rescue and fire fighting vehicles were positioned at readiness in the vicinity of the airport’s southern fire station. The weather was described as very windy with a light snow flurry. The fire fighters subsequently reported they had seen two white landing lights and the dim outline of an approaching aircraft. The aircraft’s bank attitude was seen to alter a number of times. Shortly before landing, the landing lights suddenly disappeared and the aircraft was no longer visible. The aircraft impacted the ground about 100 metres prior to the threshold of runway 26L. The crew turned off all the electrical systems and left the aircraft unaided. During the initial interviews by BFU and police the co-pilot repeatedly talked about a go-around the crew had intended and he had, therefore, pushed the power lever for the right engine forward. In later statements he stated that the engine power was to be increased. A few days after the accident, the BFU asked both pilots for a detailed written statement concerning the course of events. The BFU received documents with a short description of the accident in note form. The statements of the two pilots were almost identical in content and format.
Probable cause:
The following findings were identified:
- When the left engine was shut down, the propeller was not feathered,
- During the final approach, the speed for an approach with one shut-off engine was lower than the reference speed,
- The airplane veered to the left during power increase and became uncontrollable due to the lack of rudder effectiveness,
- Non-adherence to checklists during the shut-off of the engine and,
- Poor crew coordination.

Circumstances:
On 18 November 2009, the flight crew of an Israel Aircraft Industries Westwind 1124A aircraft, registered VH-NGA, was attempting a night approach and landing at Norfolk Island on an aeromedical flight from Apia, Samoa. On board were the pilot in command and copilot, and a doctor, nurse, patient and one passenger. On arrival, weather conditions prevented the crew from seeing the runway or its visual aids and therefore from landing. The pilot in command elected to ditch the aircraft in the sea before the aircraft’s fuel was exhausted. The aircraft broke in two after ditching. All the occupants escaped from the aircraft and were rescued by boat.
Probable cause:
The pilot in command did not plan the flight in accordance with the existing regulatory and operator requirements, precluding a full understanding and management of the potential hazards affecting the flight. The flight crew did not source the most recent Norfolk Island Airport forecast, or seek and apply other relevant weather and other information at the most relevant stage of the flight to fully inform their decision of whether to continue the flight to the island, or to divert to another destination. The flight crew’s delayed awareness of the deteriorating weather at Norfolk Island combined with incomplete flight planning to influence the decision to continue to the island, rather than divert to a suitable alternate.

Circumstances:
The Sky North Air Ltd. Beechcraft A100 (registration C-FSNA, serial number B-227) operating as SN683 departed Runway 32 at Gods Lake Narrows, Manitoba, for Thompson, Manitoba with two pilots, a flight nurse, and two patients on board. Shortly after takeoff, while in a climbing left turn, smoke and then fire emanated from the pedestal area in the cockpit. The crew continued the turn, intending to return to Runway 14 at Gods Lake Narrows. The aircraft contacted trees and came to rest in a wooded area about one-half nautical mile northwest of the airport. The accident occurred at 2140 central standard time. All five persons onboard evacuated the aircraft; two received minor injuries. At approximately 0250, the accident site was located and the occupants were evacuated. The aircraft was destroyed by impact forces and a post-crash fire. The emergency locator transmitter was consumed by the fire and whether or not it transmitted a signal is unknown.
Probable cause:
Findings as to Causes and Contributing Factors:
1. An electrical short circuit in the cockpit pedestal area produced flames and smoke, which induced the crew to take emergency action.
2. The detrimental effects of aging on the wires involved may have been a factor in this electrical arc event.
3. The crew elected to return to the airport at low level in an environment with inadequate visual references. As a result, control of the aircraft was lost at an altitude from which a recovery was not possible.
Findings as to Risk:
1. The actions specified in the standard operating procedures (SOP) do not include procedures for an electrical fire encountered at low altitude at night, which could lead to a loss of control.
2. Visual inspection procedures in accordance with normal phase inspection requirements may be inadequate to detect defects progressing within wiring bundles, increasing the risk of electrical fires.
3. In the event of an in-flight cockpit pedestal fire, the first officer does not have ready access to available fire extinguishers, reducing the likelihood of successfully fighting a fire of this nature.
4. Sealed in plastic containers and stored behind each pilot seat, the oxygen masks and goggles are time consuming to access and cumbersome to apply and activate. This could increase the probability of injury or incapacitation through extended exposure to smoke or fumes, or could deter crews from using them, especially during periods of high cockpit workload.
Other Finding:
1. A failure of the hot-mic recording function of the cockpit voice recorder (CVR) had gone undetected and information that would have been helpful to the investigation was not available.

Circumstances:
The pilot of the multiengine airplane was flying two passengers at night on an instrument-flight-rules flight plan. One of the passengers had been on an organ recipient waiting list and his wife was accompanying him. A viable matched organ was available at a distant hospital and the passenger had to arrive on short notice for surgery the following morning. All radio communications during the flight between the pilot and air traffic control (ATC), a flight service station (FSS), and a fixed-based operator (FBO) were routine. The pilot was aware of the weather at the destination airport, and had commented to ATC about 75 miles from the destination that the weather was "going up and down…like a real thin fog layer.” Additionally, better weather conditions prevailed at nearby suitable airports. The pilot mentioned one of those airports to ATC in the event he decided to divert. According to an employee at an FBO located at the destination airport, the pilot contacted him via radio and asked about the current weather conditions. The employee replied that the visibility was low due to fog and that he could not see the terminal lights from the FBO. The pilot then asked which of the two alternate airports was closer and the employee stated that he did not know. The employee then heard the pilot “click” the runway lights and contact the local FSS. about 5 miles from runway 29, just prior to the initial approach fix, the pilot radioed on the common traffic advisory frequency and reported a 5-mile final leg for runway 29. The FSS reported that the current weather was automated showing an indefinite ceiling of 100 feet vertical visibility and 1/4 mile visibility in fog. The pilota cknowledged the weather information. The weather was below the minimum published requirements for the instrument-landing-system (ILS) approach at the destination airport. Radar data showed that the flight intercepted and tracked the localizer, then intercepted the glideslope about 1 minute later. There were a few radar targets without altitude data due to intermittent Mode C transponder returns. The last recorded radar target with altitude indicated the airplane was at 600 feet, on glideslope and heading for the approach; however, the three subsequent and final targets did not show altitude information. The last recorded radar target was about 1.4 miles from the runway threshold. The airplane flew below glideslope and impacted 100-foot-tall trees about 4,150 feet from the runway 29 threshold. On-ground facility checks and a postaccident flight check of the ILS runway 29 approach conducted by the Federal Aviation Administration did not reveal malfunctions with the ILS. The cabin and cockpit area, including the NAV/COMM/APP, equipment were consumed by a postimpact fire which precluded viable component testing. Detailed examination of the wreckage that was not consumed by fire did not reveal preimpact mechanical malfunctions that may have contributed to the accident. Given that the pilot was aware of the weather conditions before and during the approach, it is possible that the pilot’s goal of expeditiously transporting a patient to a hospital for an organ transplant may have affected his decision to initiate and continue an instrument approach while the weather conditions were below the published minimum requirements for the approach.
Probable cause:
The pilot's failure to maintain the proper glidepath during an instrument-landing-system (ILS) approach. Contributing to the accident were the pilot's decision to initiate the ILS approach with weather below the published minimums, and the pilot's self-induced pressure to expeditiously transport an organ recipient to a hospital.

Circumstances:
The private pilot arrived at the accident airport as part of an Angel Flight volunteer program to provide transportation of a passenger who had undergone medical treatment at a local hospital. About 0937, the airplane landed on runway 30 (3,900 feet by 150 feet) with winds from 073-080 degrees and 5-6 knots, which continued to increase due to an atmospheric pressure gradient. The pilot met the passengers and departed the terminal about 1003, with winds at 101-103 degrees and 23-36 knots. About 1005 the airplane was near the approach end of runway 30 with wind from 089-096 degrees and 21-31 knots. The pilot stated that he began rotating the airplane about 3,000 feet down the runway. About 1006, the airplane was approximately 3,553 feet down the runway while flying about 30 feet above the runway. The airplane experienced an aerodynamic stall, and the left wing dropped before it impacted the ground. No mechanical anomalies that would have precluded normal operation of the airplane were noted during the investigation. The fatally injured passenger, who had received medical treatment, was 2 years and 10 months of age at the time of the accident. She was held by her mother during the flight, as she had been on previous Angel Flights, but was otherwise unrestrained. According to 14 CFR 91.107(3), each person on board a U.S.-registered civil aircraft must occupy an approved seat with a safety belt properly secured during takeoff, and only unrestrained children who are under the age of 2 may be held by a restrained adult. Although the accident was survivable (both the pilot and the adult passenger survived with non-life-threatening injuries), an autopsy performed on the child revealed that the cause of death was blunt force trauma of the head.
Probable cause:
The pilot's improper decision to depart with a preexisting tailwind and failure to abort takeoff. Contributing to the severity of the injuries was the failure to properly restrain (FAA-required) the child passenger.
