On September 23, 1990, a Christen Industries A-1 (registration N6082P) operated by Jack B. Poage was involved in an aviation accident near Middle River, MD. Investigators recorded the probable cause as: The pilot's loss of control during aerobatic maneuvers, which resulted in a spin and subsequent impact with the ground. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.
An aircraft performing aerobatic maneuvers at an airshow entered a spin and struck the ground. The pilot was leveling from the descent when impact occurred, with no pre-impact mechanical issues detected.
What happened
The pilot was conducting aerobatic maneuvers as part of a public airshow performance. After completing several figures, the aircraft entered an uncontrolled descent and began to spin. The airplane completed four full rotations during the spin before striking the ground. This impact occurred while the pilot was attempting to level the aircraft from the descent. Just prior to the crash, observers noted that engine sounds increased significantly.
The investigation
Investigators examined the wreckage and operational context of the accident. A thorough review found no evidence of pre-impact mechanical malfunction or failure within the aircraft's systems.
Probable cause
The pilot's loss of control during aerobatic maneuvers, which resulted in a spin and subsequent impact with the ground.
