Airport (less than 10 km from airport)

Following an uneventful flight from Salzburg, the crew was cleared to descent to Vienna-Schwechat Airport. On approach to runway 34, the crew completed the checklist and lowered the landing gear when he realized the the left main gear remained stuck in its wheel well and that the green light failed to come on on the cockpit panel. The crew agreed to continue. After touchdown on runway 34, the aircraft deviated to the left, veered off runway and came to rest in a grassy area located near taxiway D and taxiway B5 and B6. All five occupants evacuated safely and the aircraft was damaged beyond repair.

The single engine aircraft departed Casale Monferrato-Francesco Cappa Airfield on a local skydiving mission, the 13th sortie of the day, carrying seven skydivers, three tourists and one pilot). Shortly after rotation from a grassy runway, the pilot encountered engine problems. The aircraft continued in a flat attitude, collided with a hedge and few trees before coming to rest in a wooded area located 300 metres past the runway end. All 11 occupants were injured, some of them seriously. The aircraft was damaged beyond repair.

On 28 August 2015 a Boeing 737-300 Freighter, registered PK-BBY was being operated by PT. Cardig Air on a scheduled cargo flight from Sentani Airport (WAJJ) Jayapura to Wamena Airport (WAVV) Papua, Indonesia. At 1234 LT (0334 UTC), the aircraft departed to Wamena and on board the aircraft were two pilots, and 14,610 kg of cargo. The Pilot in Command (PIC) acted as Pilot Flying (PF) while the Second in Command (SIC) who was under line training acted as Pilot Monitoring (PM). There was no reported or recorded aircraft system abnormality during the flight until the time of occurrence. At 0637 UTC, when the aircraft approaching PASS VALLEY, the Wamena Tower controller provided information that the runway in use was runway 15 and the wind was 150°/18 knots, QNH was 1,003 mbs and temperature was 23 °C. At 0639 UTC, the pilot reported position over PASS VALLEY, descended passing FL135. The Wamena Tower controller instructed the pilot to report position over JIWIKA. At 0645 UTC, the pilot reported position over JIWIKA and continued to final runway 15. At 0646 UTC, the pilot reported position on final runway 15 and Wamena Tower controller provided landing clearance with additional information of wind 150°/15 knots and QNH 1,003 mbs. At 0647 UTC, the aircraft touched down about 35 meter before the beginning runway 15 with vertical acceleration of 3.68 G. The left main landing gear collapsed and the left engine contacted to the runway surface. The aircraft stopped at about 1,500 meters from runway threshold. No one was injured on this occurrence.

Shortly after takeoff in day visual meteorological conditions, when the airplane was climbing through 3,000 ft mean sea level, a complete electrical failure occurred that affected electrical instrumentation and additional airplane equipment, including the landing gear. The pilot reported that he performed the electrical failure checklists and could not restore power. After additional troubleshooting with no success, he chose to divert to and land at another airport. While in the traffic pattern at his diversion airport, he attempted to lower the landing gear using the emergency landing gear extension procedures but could not confirm the landing gear were down and locked. Without any capability to communicate or confirmation that the landing gear were down, he decided to leave the airport traffic pattern and land on a nearby field to avoid airport traffic; the airplane sustained substantial damage to the fuselage, landing gear doors, engines, and propellers during the off-airport landing. The reason for the loss of electrical power could not be determined. Examination of the cockpit revealed that the landing gear's emergency engage handle, also known as the "J" handle, was not pulled up and turned, which was one of the steps listed in the airplane flight manual for the manual landing gear extension procedure. The "J" handle engages the clutch and allows for the handle to operate the landing gear chain. Without engaging the "J" handle, the landing gear handle pumping action would not have worked, which resulted in the gear-up landing.

The crew was apparently completing a positioning flight to Toluca Airport. Following a night landing on runway 15, the crew started the braking procedure when the aircraft deviated to the left. The crew applied full brake but the aircraft veered off runway. While contacting soft ground, the nose gear collapsed and the aircraft came to rest about 2,700 metres from the runway threshold. Both pilots escaped uninjured and the aircraft was damaged beyond repair.

The crew was performing a charter flight from Oranjestad (Aruba) to Charallave with an intermediate stop in Barcelona. While on a night approach to runway 10, the captain initiated a go-around procedure for unknown reasons. During the second attempt to land, the aircraft landed long and the touchdown point appeared to be half way down the runway 10 which is 2,000 meters long. Unable to stop within the remaining distance, the aircraft overran, went down an embankment and came to rest. All eight occupants evacuated safely while the aircraft was damaged beyond repair. The passengers were members of the pop band 'Los Cadillac's' accompanied by the Venezuelan singer and actor Arán de las Casas.

After the airplane touched down on the 4,422-ft-long runway, the airline transport pilot applied the brakes to decelerate; however, he did not think that the brakes were operating. He continued "pumping the brakes" and considered conducting a go-around; however, there was insufficient remaining runway to do so. The airplane subsequently continued off the end of the runway, impacted a berm, and came to rest upright, which resulted in substantial damage to the right wing. During postaccident examination of the airplane, brake pressure was obtained on both sets of brake pedals when they were depressed, and there was no bleed down or reduction in pedal firmness when the brakes were pumped several times. Examination revealed no evidence off any preimpact anomalies with the brake system that would have precluded normal operation. In addition, the pilot indicated that he was not aware of and was not trained on the use of the ALL INTERRUPT button, which is listed as a step in the Emergency Procedures section of the airplane flight manual and is used to disable the anti-skid brake system functions and restore normal braking when the brakes are ineffective; thus, the pilot did not follow proper checklist procedures. According to data downloaded from the airplane's diagnostic storage unit (DSU), the airplane touched down 1,280 ft beyond the runway threshold, which resulted in 2,408 ft of runway remaining (the runway had a displaced threshold of 734 ft) and that it traveled 2,600 ft before coming to rest about 200 ft past the runway. The airplane's touchdown speed was about 91 knots. Comparing DSU data from previous downloaded flights revealed that the airplane's calculated deceleration rate during the accident landing was indicative of braking performance as well as or better than the previous landings. Estimated landing distance calculations revealed that the airplane required about 3,063 ft when crossing the threshold at 50 ft above ground level. The target touchdown speed was 76 knots. However, the airplane touched down with only 2,408 ft of remaining runway faster than the target touchdown speed, which resulted in the runway overrun.

On 16 August 2015, a Maritime Air Charter Limited Beechcraft King Air A100 (registration C-FDOR, serial number B-103) was on a charter flight from Halifax Stanfield International Airport, Nova Scotia, to Margaree Aerodrome, Nova Scotia, with 2 pilots and 2 passengers on board. At approximately 1616 Atlantic Daylight Time, while conducting a visual approach to Runway 01, the aircraft touched down hard about 263 feet beyond the threshold. Almost immediately, the right main landing gear collapsed, then the right propeller and wing contacted the runway. The aircraft slid along the runway for about 1350 feet, then veered right and departed off the side of the runway. It came to rest about 1850 feet beyond the threshold and 22 feet from the runway edge. There were no injuries and there was no post-impact fire. The aircraft was substantially damaged. The occurrence took place during daylight hours. The 406-megahertz emergency locator transmitter did not activate.

The Cessna 172 (N1285U) was conducting touch-and-go landings at Brown Field Municipal Airport (SDM), San Diego, California, and the experimental North American Rockwell NA265-60SC Sabreliner (N442RM, call sign Eagle1) was returning to SDM from a mission flight. SDM has two parallel runways, 8R/26L and 8L/26R; it is common in west operations for controllers to use a right traffic pattern for both runways 26R and 26L due to the proximity of Tijuana Airport, Tijuana, Mexico, to the south of SDM. On the morning of the accident, the air traffic control tower (ATCT) at SDM had both control positions (local and ground control) in the tower combined at the local control position, which was staffed by a local controller (LC)/controller-in-charge, who was conducting on-the-job training with a developmental controller (LC trainee). The LC trainee was transmitting control instructions for all operations; however, the LC was monitoring the LC trainee's actions and was responsible for all activity at that position. About 13 minutes before the accident, the N1285U pilot contacted the ATCT and requested touch-andgo landings in the visual flight rules (VFR) traffic pattern. About that time, another Cessna 172 (N6ZP) and a helicopter (N8360R) were conducting operations in the VFR traffic pattern, and a Cessna 206 Stationair (N5058U) was inbound for landing. Over the next 5 minutes, traffic increased, with two additional aircraft inbound for landing. (Figure 1 in the factual report for this accident shows the aircraft in the SDM traffic pattern about 8 minutes before the accident.) The LC trainee cleared the N1285U pilot for a touch-and-go on runway 26R; the pilot acknowledged the clearance and then advised the LC trainee that he was going to go around. The LC trainee advised the N1285U pilot to expect runway 26L on the next approach. At that time, three aircraft were using runway 26R (Global Express [N18WZ] was inbound for landing, N6ZP was on a right base for a touch-and-go, and a Cessna Citation [XALVV] was on short final) and three aircraft were using runway 26L (N1285U was turning right downwind for the touch-and-go, a Skybolt [N81962] was on a left downwind for landing, and N8360R was conducting a touch-and-go landing). After N1285U completed the touch-andgo on runway 26L, the pilot entered a right downwind for runway 26R. Meanwhile, Eagle1 was 9 miles west of the airport and requested a full-stop landing; the LC trainee instructed the Eagle1 flight crew to enter a right downwind for runway 26R at or above an altitude of 2,000 ft mean sea level. At this time, about 3 minutes before the accident, the qualified LC terminated the LC trainee's training and took over control of radio communications. From this time until the collision occurred, the LC was controlling nine aircraft. (Figure 2 and Figure 4 in the factual report for this accident show the total number of aircraft under ATCT control shortly before the accident.) During the next 2 minutes, the LC made several errors. For example, after N6ZP completed a touch-andgo on runway 26R, the pilot requested a right downwind departure from the area, which the LC initially failed to acknowledge. The LC also instructed the N5058U pilot, who had been holding short of runway 26L, that he was cleared for takeoff from runway 26R. Both errors were corrected. In addition, the LC instructed the helicopter pilot to "listen up. turn crosswind" before correcting the instruction 4 seconds later to "turn base." (Figure 2 in the factual report for this accident shows the aircraft in the traffic pattern about 2 minutes before the accident.) About 1 minute before the collision, the Eagle1 flight crew reported on downwind midfield and stated that they had traffic to the left and right in sight. At that time, N1285U was to Eagle1's right, between Eagle1 and the tower, and established on a right downwind about 500 ft below Eagle1's position. N6ZP was about 1 mile forward and to the left of Eagle1, heading northeast and departing the area. Mistakenly identifying the Cessna to the right of Eagle1 as N6ZP, the LC instructed the N6ZP pilot to make a right 360° turn to rejoin the downwind when, in fact, N1285U was the airplane to the right of Eagle1. (The LC stated in a postaccident interview that he thought the turn would resolve the conflict with Eagle1 and would help the Cessna avoid Eagle1's wake turbulence.) The N6ZP pilot acknowledged the LC's instruction and began turning; N1285U continued its approach to runway 26R. However, the LC never visually confirmed that the Cessna to Eagle1's right (N1285U) was making the 360° turn. Ten seconds later, the LC instructed the Eagle1 flight crew to turn base and land on runway 26R, which put the accident airplanes on a collision course. The LC looked to ensure that Eagle1 was turning as instructed and noticed that the Cessna on the right downwind (which he still mistakenly identified as N6ZP) had not begun the 360° turn that he had issued. The LC called the N6ZP pilot, and the pilot responded that he was turning. In the first communication between the LC and the N1285U pilot (and the first between the controllers in the ATCT and that airplane's pilot in almost 6 minutes), the LC transmitted the call sign of N1285U, which the pilot acknowledged. N1285U and Eagle1 collided as the LC tried to verify N1285U's position. A postaccident examination of both airplanes did not reveal any mechanical anomalies that would have prevented the airplanes from maneuvering to avoid an impact.

On 12 August 2015, a PAC-750XL aircraft, registered PK-KIG, was being operated by PT. Komala Indonesia on an unscheduled passenger flight from Wamena Airport (WAJW) Papua to Ninia Airstrip , Yahukimo, Papua that was located on radial 127° from Wamena with a distance of approximately 26 Nm. At 0733 LT (2233 UTC), the aircraft departed from Wamena Airport with an estimated time of arrival at Ninia of 2248 UTC. The flight was uneventful until approaching Ninia. On board the aircraft were one pilot, one engineer and 4 passengers. According to the pilot statement, an airspeed indicator malfunction occurred during flight. Video footage taken by a passenger showed that, during the approach at an altitude of approximately 6,500 feet, the airspeed indicators indicated zero and the aural stall warning activated. The aircraft then flew on the left side and parallel to the runway. Thereafter the aircraft climbed, turned left and impacted the ground about 200 meters south-west of the runway. The engineer on board was fatally injured, one passenger had minor injuries and the other occupants, including the pilot, were seriously injured. Two occupants were evacuated to a hospital in Jayapura Airport and four others, including the fatally injured, were evacuated to a hospital in Wamena.
