1985-09-14: Ryan NAVION (N91460) — Midland, TX

Midland, TX, US

On September 14, 1985, a Ryan NAVION (registration N91460) was involved in an aviation accident near Midland, TX. Investigators recorded the probable cause as: The undetermined failure of a connecting rod, which resulted in an engine failure during climbout. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.

A pilot experienced an engine failure during climbout from Sky Ranch Airport in Midland, Texas, resulting in a forced landing with the gear retracted.

What happened

The pilot was operating an aircraft during the initial climbout phase from Sky Ranch Airport (KMYF) in Midland, Texas. Shortly after takeoff, the engine failed, leaving the pilot without power. In response to the emergency, the pilot executed a turn into the wind to maintain airspeed and control. The pilot then selected a pasture as a landing site and proceeded with a forced landing. During the approach, the pilot had already retracted the landing gear. Consequently, the aircraft touched down on its belly onto wet terrain in the pasture.

The investigation

A subsequent mechanical examination of the aircraft was conducted to determine the cause of the power loss. Inspectors discovered that a connecting rod within the engine had broken. This structural failure is consistent with the reported sudden loss of engine power during flight.

Findings

The investigation confirmed the mechanical nature of the failure but could not pinpoint the root origin of the component breakage. The cause of the connecting rod failure remained undetermined after thorough inspection. Additionally, the aircraft sustained damage from the gear-up contact with the ground. The pilot's decision to retract the gear prior to touchdown contributed to the extent of the airframe damage.

Safety message

This incident highlights the critical importance of engine maintenance and inspection protocols to prevent in-flight mechanical failures. It also underscores the need for pilots to consider gear configuration carefully during emergency landings, as extending the landing gear can often reduce impact forces and improve survivability.

Probable cause

The undetermined failure of a connecting rod, which resulted in an engine failure during climbout.
