Aircraft involved
Probable cause & findings
The pilot's failure to maintain adequate airspeed which resulted in an inadvertent stall and inflight collision with the terrain. A factor was the proper touchdown point was not obtained.
Factual narrative
On Sunday, August 22, 1993, at about 1115 eastern daylight time, a Cessna 182G, N23PM, piloted by Mr. Erdman Hoffman, collided with the terrain while landing at the Slattington Airport, Slattington, Pennsylvania. The airplane was substantially damaged. The pilot was seriously injured, and the three passengers received minor injures. Visual meteorological conditions prevailed at the time and no flight plan had been filed. The flight was being conducted under 14 CFR 91. According to the pilot's statement on the NTSB Form 6120.1/2: ...on final...I had a cross wind to the right towards the trees...[I] had full flaps...touched down with stall horn just starting to come on...decided to abort landing as I was unable to...correct for cross wind...increased throttle...raised flaps...hit top of trees with left wing. FAA Inspector, Robert Shapiro said ...the accident site was midfield up Runway 01 and right of the runway which consisted of trees and a river bank...the aircraft came to rest on a river bank with the nose in the river and the aircraft inverted...the inboard runway end light at the approach end of Runway 01 was struck by the aircraft during the landing prior to the attempted go around...continuity was noted on all control systems...the engine was inspected...no malfunction of the engine was evident...the pilot...was interviewed...and he stated, "I stalled the aircraft"..."I was slow to get the flaps up"..."the engine ran great and...there was no malfunction"... DURING THE LANDING THE AIRPLANE TOUCHED DOWN SHORT OF THE APPROACH END OF RUNWAY 01, AND STRUCK THE RIGHT INBOARD RUNWAY END LIGHTS. THE PILOT THEN ABORTED THE LANDING AND HE INITIATED A GO AROUND. ACCORDING TO THE PILOT, DURING THE CLIMB THE AIRPLANE STALLED. THE AIRPLANE STRUCK TREES AND CAME TO REST INVERTED. Source: NTSB Aviation Accident Database (Pre-2008 Archive) Retrieved: 2026-02-12
