From the FAA’s Accident/Incident Data System (AIDS), through its Aviation Safety Information Portal, as reported. The NTSB investigates accidents separately, and its record of an accident is the fuller one. The aircraft is matched to the registry by N-number and event date, checked against the reported make and model; the registry’s history has gaps, so older matches can be wrong. Compare the reported make and model.

What happened

The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.

On Monday, July 01, 2019, N387G, a Grumman AA-5A cheetah, operated by a commercial rated pilot with a commercial rated pilot as a passenger, was en route to rocky mountain metropolitan airport (kbjc) from casper, WY (kcpr). Monitoring the severe weather conditions at kbjc in flight, they decided to divert to Cheyenne, WY (kcys).

Approximately 2100 MDT in night VMC conditions, N387G was on final for runway 27 at kcys. The pilot-in-command (PIC) and passenger reported during the transition to the roundout, she saw a nose level attitude and 65 KIAS on the airspeed gauge. Then the stall horn sounded, the aircraft rapidly descended and developed a high sink rate. The PIC executed a go-around procedure but aircraft impacted the runway flat, the nose veered left and the aircraft was airborne again. The PIC attempted to regain runway centerline and the aircraft struck obstacles left of the runway impacting the wing and the bottom of the fuselage. When a go-around was not possible due the aircraft?s inability to climb, the PIC reduced power and landed the aircraft in a grassy area to the left of runway 27 and short of a taxiway.

Impact with the obstacle resulted in damage to the bottom of the fuselage, damage to the left hand wing, including the left hand flap being bent upward creating an asymmetrical flaps, and damage to the left hand horizontal stabilizer and left hand elevator.
