On October 23, 1984, a Piper PA-38-112 (registration N9844T) was involved in an aviation accident near Minneapolis, MN. Investigators recorded the probable cause as: The pilot's preoccupation with the loose engine cowling caused him to allow the aircraft to enter a steep bank, which led to an aerodynamic stall. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.
During initial climb, the pilot noticed a loose and vibrating engine cowling. While executing a shallow turn back for landing, preoccupation with the cowling caused the aircraft to enter a steep bank, leading to an aerodynamic stall and uncontrolled descent.
Occurrence
During the initial climb after takeoff, the pilot observed that the engine cowling was loose and vibrating. In response, the pilot initiated a shallow turn to return to the airport for landing.
Pilot Actions
While preoccupied with the loose cowling, the pilot inadvertently allowed the aircraft to enter a steep bank. Attempting to reduce the bank angle, the pilot heard the stall warning horn activate. The pilot then increased back pressure on the elevator control and applied right rudder. The aircraft subsequently stalled and descended to the ground in uncontrolled flight.
Conclusion
The pilot's preoccupation with the loose engine cowling led to a loss of control resulting in a stall.
Probable cause
The pilot's preoccupation with the loose engine cowling caused him to allow the aircraft to enter a steep bank, which led to an aerodynamic stall.
