Category:Accident
Location:Salisbury-Ocean City Wicomico Regional Airport, Salisbury, Maryland -   United States of America
Phase: Approach
Nature:Unknown
Departure airport:SBY
Destination airport:Wilkes-barre, PA (AVP)
Investigating agency: NTSB
Narrative:
After takeoff, the right engine 'started surging' and the pilot turned back toward the departure airport. He configured the airplane for landing, and then attempted to secure the right engine. The engine seized, and the propeller stopped. The airplane was unable to maintain altitude sufficient to clear trees at the approach end of the landing runway, and the pilot performed a forced landing to a field approximately 1 mile short of the airport. The #2 cylinder of the right engine was replaced 160 aircraft hours prior to the accident. Examination of the right engine revealed the crankshaft was broken between the #2 main bearing journal and the #3 connecting rod journal. The mating surfaces of both crankcase halves, in the area of the #2 and #3 main bearing saddles, displayed fretting across the entire face surface. Examination of the fracture surfaces revealed that the damage was consistent with bearing shifting and rubbing. A warning published in the manufacturer's cylinder installation instructions stated: 'Failure to torque through bolt nuts on both sides of the engine can result in a loss of main bearing crush, main bearing shift and engine failure.' According to the FAA Airplane Flying Handbook, Engine Inoperative Approach And Landing: '...neither full flaps nor the landing gear should be extended until the landing is assured.'

Probable Cause: The improper installation of the #2 cylinder that resulted in a fractured crankshaft and a total loss of engine power. Factors in the accident were the premature deployment of the landing gear and flaps by the pilot.
