On February 23, 1986, a Cessna 402B (registration N4605N) was involved in an aviation accident near Plainview, TX. Investigators recorded the probable cause as: The pilot's improper approach during a practice single-engine procedure, which necessitated a gear-up landing because a go-around was not feasible with an intentionally inoperative engine. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.
A pilot conducting a practice single-engine procedure aborted a landing due to an improper approach, then executed a controlled gear-up landing after realizing a go-around was not viable.
What happened
The aircraft landed on its belly following a practice single-engine procedure. The pilot initiated an attempt to abort the landing and execute a go-around. However, the approach had become improper, making the go-around impractical given that one engine was intentionally inoperative. Upon recognizing this limitation, the pilot concluded the flight by landing gear-up at the airport.
The investigation
The sequence of events indicates that the pilot's decision to land gear-up was a direct result of the constraints imposed by the practice scenario. With an engine intentionally inoperative, the performance margins required for a safe go-around were not available once the approach deviated from standard parameters.
Findings
improper approach during a practice single-engine procedure
go-around not practical due to intentionally inoperative engine
landing gear-up as the only viable conclusion to the flight
Probable cause
The pilot's improper approach during a practice single-engine procedure, which necessitated a gear-up landing because a go-around was not feasible with an intentionally inoperative engine.
