Aircraft crash in Inkster following takeoff from Detroit

No fatalities • Detroit-Metropolitan-Wayne County, United States of America • Takeoff (climb)

An aircraft crashed in Inkster, Michigan, during its initial climb phase after experiencing instability and failing to maintain altitude.

What happened

During the initial climb phase following departure from Detroit-Wayne County Airport, the flight crew experienced significant mechanical or aerodynamic difficulties. The aircraft became unstable and was unable to reach a sufficient altitude. This loss of performance led to an aerodynamic stall, resulting in the plane crashing in the Inkster area, located north of the airport. The impact resulted in the total destruction of the aircraft and left four occupants with serious injuries.

Findings

Investigations into the accident identified several critical contributing factors related to both operational oversight and physical loading. The aircraft was operating at a total weight that exceeded its maximum allowable gross weight by 1,727 lbs. Additionally, the center of gravity (CofG) was measured at 9.26 inches beyond the permitted maximum limits. This improper loading prevented the crew from reducing the angle of attack to achieve the necessary V2 speed during the climb.

Further findings pointed toward systemic organizational failures, including improperly loaded aircraft-weight and/or CofG as a primary factor alongside inadequate flight crew supervision. The investigation also noted deficiencies in company maintenance, equipment, and regulatory services, as well as insufficient preflight planning and a lack of proper directives or manuals provided to the crew.

Probable cause

The accident was driven by an overweight aircraft with an out-of-limits center of gravity combined with inadequate operational oversight and preparation.
