Circumstances:
A Galaxy Airlines Lockheed L-188A Electra, registration N5532, was scheduled operate flights from Seattle (SEA) to Oakland as Flight 201, from Oakland to Reno (RNO) as Flight 202, from Reno (RNO) to Minneapolis (MSP) as Flight 203 and finally returning to Seattle using flight number 204. Scheduled departure time for Flight 201 had been 15:30, but had been delayed and the airplane departed Seattle at 20:19 on a ferry flight to Oakland, where it arrived at 22:25. Sixty-five passengers boarded the plane for the flight to Reno. Following ground servicing the ground handler supervisor signalled to the crew that they could commence engine starting. However, after engines one and four were started, he noticed that the other ground handler was unable to disconnect the air start hose. It was stretched taut from the power cart to the airplane’s air start access panel, located on the underside of the right wing leading edge, close to the fillet area. The supervisor gave the flightcrew an emergency stop signal, left his position, and disconnected the hose. None of the two ground crew members remembered closing the air start access door. At approximately 00:59 the first officer requested taxi instructions Reno tower almost immediately thereafter cleared Galaxy 203 to taxi to runway 16R. The aircraft taxied to the runway and at 01:01:32 the first officer requested takeoff clearance. Four seconds later Galaxy 203 was given clearance to take off from runway 16R. While accelerating through V1 speed, a "thunking" type sound was heard, followed by another one just after V2. Heavy airframe vibration started after liftoff. The captain reacted to the airplane’s vibration by reducing power significantly in all four engines, indicating that he believed the vibration was caused by the powerplants or propellers. The airplane reached an altitude of about 200-250 feet and started a right hand turn to return to the airport. The Electra then entered an aerodynamic stall buffet because of insufficient engine power to maintain flight. The Electra crashed into a field, bounced, slid into some mobile homes and burst into flames. Of the 71 occupants, three initially survived the crash. One died on January 29, while the second died of injuries on February 4. The sole survivor, a 17-year-old male, was thrown clear of the airplane onto the adjacent highway.
Probable cause:
The captain's failure to control and the co-pilot's failure to monitor the flight path and airspeed of the aircraft. This breakdown in crew coordination followed the onset of unexpected vibration shortly after takeoff. Contributing to the accident was the failure of ground handlers to properly close an air start access door, which led to the vibration.

Circumstances:
During arrival to the Kansas City Downtown Airport, the flight was vectored for a VOR runway 03 approach, then was cleared for the approach and to circle and land on runway 36. On final approach, the aircraft was high and was not in a position to land, so the flight was cleared to circle left for another approach to land. The aircrew acknowledged and began circling left which took them in the vicinity of the Fairfax Airport. A short time later, the ATC controller cautioned that the flight might be lining up for the Fairfax Airport. Subsequently, the crew initiated a missed approach and were instructed to turn to 360° and climb to 3,000 feet. The aircraft began a steep climb to 3,100 feet, stalled and entered a steep descent. Before the descent was arrested, the aircraft impacted in a public water treatment plant. CVR recordings indicated that the 1st officer was flying the aircraft during the en route descent, VOR approach and circling approach, then the captain took control during the missed approach. An exam of the wreckage revealed no evidence of an airframe or powerplant problem. Also, there was no evidence that the cargo had shifted. All three crew members were killed.
Probable cause:
Occurrence #1: loss of control - in flight
Phase of operation: missed approach (ifr)

Circumstances:
Zantop ground personnel completed the loading of Flight 931 at 00:40. All cargo was bulk loaded and tied down on the right side of the airplane for the full length of the cargo compartment. Flight 931 departed the gate at Baltimore/Washington International Airport at 01:05 and took off on runway 28 at 01:10. At 01:11:42, Flight 931 contacted Baltimore departure control and was cleared to 13,000 feet. After switching to Washington ARTCC, the flight was cleared further FL220. At 01:32 a no. 2 gyro malfunction made the crew select the no. 1 gyro to drive both approach horizons and the problem appeared resolved. At 01:43:09, Cleveland ARTCC cleared Flight 931 direct to the Dryer VOR. After the turn to the Dryer VOR, the first officer’s approach horizon may have displayed incorrect pitch and roll information. The flightcrew may have received conflicting pitch and roll information from the two approach horizons as they attempted to recover from an unusual attitude. The flightcrew overstressed the airplane in an attempt to recover from the unusual attitude as the aircraft spiralled down. The Electra broke up and falling wreckage damaged some houses; however, most of the wreckage fell in uninhabited, wooded areas.
Probable cause:
The aircraft's entry into an unusual attitude and the inability of the flight crew to analyse the flight condition before there was a complete loss of control. Although the precise reason for the loss of control was not identified, an undetermined failure of a component in the No.2 vertical gyro system, perhaps involving the amplifier and associated circuitry, probably contributed to the cause of the accident by incorrectly processing data to the co-pilot's approach horizon. The in-flight structural failure of the aircraft was due to overload.

Circumstances:
Prior to takeoff from Guatemala City to Tegucigalpa, one of the engine failed as well as a generator. Passengers were disembarked and the captain decided to fly to Tegucigalpa on three engines only. Less than one minute after takeoff, while climbing, the pilot reported a critical situation and requested an immediate return. While making a last turn, the airplane lost height and crashed on a residential area located 1,500 meters from the airport, bursting into flames. All six occupants were killed and 38 people on ground were injured. The aircraft and several houses were destroyed.
Probable cause:
It was determined that a second generator failed during initial climb for unknown reasons. Due to insufficient power, hydraulic pressure dropped below minimums, causing the airspeed to drop and the aircraft to stall. The fact that the aircraft was not correctly trimmed was considered as a contributing factor.

Circumstances:
The four engine airplane departed Ogden-Hill AFB at 0445LT on a cargo flight to Nellis AFB on behalf of the USAF, carrying three crew members and 27,552 lbs of cargo. While climbing from 12,000 to 13,000 feet, the flight indicated to Salt Lake departure control that they had lost all electrical power, the flight requested no-gyro vectors to visual flight conditions and clearance for an immediate descent to a lower altitude. During the descent, the aircraft attained a high airspeed and high rate of descent and disintegrated in flight. The three crewmembers were killed and the aircraft was destroyed. The wreckage was dispersed along a path about 1 1/2 miles long on an abandoned airport located about 4 nmi south of the Salt Lake City International Airport.
Probable cause:
The National Transportation Safety Board determines that the probable cause of this accident was a progressive failure in the aircraft's electrical system leading to the disabling or erratic performance of some critical flight instruments and flight instrument lighting while the flight was operating in night instrument meteorological conditions. As a result of these conditions, the flightcrew could not resolve the instrumentation anomalies to determine proper aircraft attitude reference, and became disoriented and lost control of the aircraft. The crew's efforts to regain control of the aircraft imDOSed aerodynamic loads which exceeded design limits of the ahraft and caused it to break up in flight.

Circumstances:
The aircraft lifted off the 10,015-foot runway about 7,500 feet down the runway. During or just after liftoff the n°3 propeller was feathered. The aircraft climbed to 100 feet while yawing to the right. The crew retracted the landing gear and flaps before the aircraft reached the apex of the climb. It then rotated to a nose-high attitude, appeared to become laterally unstable, and struck the rising terrain in a tail-low attitude. Impact was about 4,300 feet beyond the end of the runway. The aft portion of the aircraft fuselage dragged along the ground for 220 feet in a right wing down attitude, after which the aircraft slid off the brow of a 13-foot embankment, crashed through the chain link perimeter fence at Agana NAS, crossed a highway, and burst into flames. The aircraft came to rest in an open area between residential areas, about 4,900 feet beyond the end of runway 06L. As the aircraft slid across the highway, it struck an automobile on the highway; the driver of the car was killed. A woman and her son, who were standing outside their residence just south of the impact site, were seriously burned by the heat of the burning fuel and were seriously injured by flying debris. All 45 occupants on board the Electra were killed.
Probable cause:
he loss of climb capability after the crew retracted the flaps at too low an altitude to clear the rising terrain. The flaps were retracted after the no.3 propeller feathered as the aircraft lifted off the runway. Contributing to the accident was the captain's decision to continue the take-off after an engine failed before reaching the rotation speed.
