The Start Operability Bleed Valve (OBV) fuel return adapter-fitting fractured and separated in cyclic fatigue, which allowed fuel to spill onto a hot engine case that ignited the undercowl fire. The OBV fuel adapter-fitting was dropped and the damage reduced its load carrying and fatigue capability, eventually leading to its failure.

Operated by ATLANTIC SOUTHEAST AIRLINES INC (per NTSB report)

The improperly installed upper attachment bolt in the left main landing gear uplock assembly, which led to the failure of the left main landing gear to extend before landing. Contributing to the accident was maintenance personnel's lack of training on the installation and inspection of the uplock assembly.

the B767 flight crew's failure to maintain a safe clearance with the CRJ900 that was stopped on a taxiway.

Operated by Atlantic Southeast Airlines Inc (per NTSB report)

The probable cause of the incident was the restriction of the right main landing gear door against the fuselage wheel well body fairing which prevented the extension of the right main landing gear.

Operated by Atlantic Southeast Airlines (per NTSB report)

The failure of the left main landing gear to extend due to high levels of particulate contamination in the hydraulic fluid.

An electrical anomaly in the top portion of the JB-1 junction box resulting in ignition of adjacent combustible materials, including insulation blankets, and a flexible oxygen line.

Operated by Atlantic Southeast Airlines, Inc. (per NTSB report)

Excessive wear on the bushings and the right aileron inboard and outboard power control unit output link resulting in the upward movement of the right aileron during cruise climb, uncommanded right roll. A factor in the accident was inadequate maintenance inspection procedure by the aircraft manufacture for the aileron system backlash check performed by the operator. The inspection procedure did not require the operator to record the tolerance found during the backlash check.

Operated by Atlantic Southeast Airlines, Inc. (per NTSB report)

Failure of the left main landing gear fitting due to a fatigue crack that emanated from multiple origins at the external surface of the wall at the shock strut radius run out area for undetermined reasons.

Operated by ATLANTIC SOUTHEAST AIRLINES (per NTSB report)

the in-flight fatigue fracture and separation of a propeller blade resulting in distortion of the left engine nacelle, causing excessive drag, loss of wing lift, and reduced directional control of the airplane. The fracture was caused by a fatigue crack from multiple corrosion pits that were not discovered by Hamilton Standard because of inadequate and ineffective corporate inspection and repair techniques, training, documentation, and communications. Contributing to the accident was Hamilton Standard's and FAA's failure to require recurrent on-wing ultrasonic inspections of the affected propellers. Contributing to the severity of the accident was the overcast cloud ceiling at the accident site.

FIRE DUE TO THE INTERNAL FAILURE OF THE NUMBER ONE DC STARTER-GENERATOR.

Operated by ATLANTIC SOUTHEAST AIRLINES (per NTSB report)

THE LOSS OF CONTROL IN FLIGHT AS A RESULT OF A MALFUNCTION OF THE LEFT ENGINE PROPELLER CONTROL UNIT WHICH ALLOWED THE PROPELLER BLADE ANGLES TO GO BELOW THE FLIGHT IDLE POSITION. CONTRIBUTING TO THE ACCIDENT WAS THE DEFICIENT DESIGN OF THE PROPELLER CONTROL UNIT BY HAMILTON STANDARD AND THE APPROVAL OF THE DESIGN BY THE FEDERAL AVIATION ADMINISTRATION. THE DESIGN DID NOT CORRECTLY EVALUATE THE FAILURE MODE THAT OCCURRED DURING THIS FLIGHT, WHICH RESULTED IN AN UNCOMMANDED AND UNCORRECTABLE MOVEMENT OF THE BLADES OF THE AIRPLANE'S LEFT PROPELLER BELOW THE FLIGHT IDLE POSITION.
