The
National Transportation Safety Board (NTSB) determined that the probable cause of the crash was a partial loss of power from one engine during the initial climb, followed by a loss of control due to improper response by the pilot. The NTSB found several contributing factors: • The aircraft was overloaded by approximately 195 pounds beyond its maximum allowable takeoff weight. • The pilot failed to retract the landing gear and flaps, contributing to increased drag and reduced climb performance. • The pilot did not abort the takeoff when engine performance issues were first observed. • The airline's training, certification, and supervision practices were found to be inadequate. The accident resulted in three recommendations: • Require that pilots operating under 14 CFR Part 135 receive comprehensive training on aircraft performance and handling characteristics when operating at or near the maximum certificated gross weight and/or at the limits of the center of gravity (CG) envelope. • In collaboration with industry stakeholders, develop flight data recorder (FDR) standards for complex aircraft that reflect their intended operational use. • Initiate the drafting of specifications and provide funding for the research and development of affordable flight data recorders (FDRs), cockpit voice recorders (CVRs), and combined recording systems suitable for complex general aviation aircraft. Establish guidelines for these systems, including a cost ceiling appropriate to the aircraft's price and its intended operational role. == References ==
