NTSB Accidents

The pilot’s failure to extend the landing gear prior to landing, which resulted in substantial damage to the lower fuselage. Contributing to the accident was the pilot’s failure to utilize the aircraft checklist.

A complete loss of engine power due to oil starvation as a result of the oil filter safety wire fracturing and the oil filter becoming loose in flight for a reason that could not be determined given the evidence available during the investigation.

The airplane’s encounter with gusting wind conditions and low-level wind shear on final approach, which resulted in a loss of control, an aerodynamic stall, and a subsequent hard landing.

Maintenance personnel’s failure to use the correct throttle linkage hardware when reinstalling the engine, resulting in a disconnection of the throttle during flight.

The pilot’s exceedance of the wing’s critical angle of attack, which resulted in an aerodynamic stall and loss of aircraft control.

A loss of directional control and subsequent runway excursion resulting as a result of the inadvertent rudder input by the passenger.

A total loss of engine power as a result of fuel starvation. Contributing to the accident was the pilot’s failure to properly manage the fuel on board the airplane and his failure to perform an adequate preflight inspection.

The pilot’s decision to depart shortly after a landing helicopter, which resulted in an encounter with the helicopter’s wake turbulence and a loss of airplane control. Contributing to the accident was the pilot’s impairment by his recent use of ethanol.

The pilot and flight instructor’s failure to ensure that the landing gear were extended prior to landing.
