## Probable cause

THE PILOT'S IMPROPER RECOVERY FROM A BOUNCED LANDING.  A FACTOR RELATED TO THE ACCIDENT WAS: THE PILOT'S IMPROPER FLARE FOR LANDING.

## Sequence of events

In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf).

- Hard landing, landing - flare/touchdown
  - flare - improper, pilot in command (contributing factor)
- In flight collision with object, go-around (vfr)
  - go-around - initiated, pilot in command
  - recovery from bounced landing - improper, pilot in command (cause)
  - airspeed - not attained, pilot in command
  - object - fence
  - proper alignment - not maintained, pilot in command

## Analysis

THE PILOT STATED THE AIRPLANE BOUNCED ON TOUCHDOWN AND HE ATTEMPTED A GO-AROUND.  A GROUND WITNESS REPORTED THE AIRPLANE'S ATTITUDE WAS ABOUT 30 DEGREES NOSE UP DURING THE GO-AROUND.  REPORTEDLY, THE AIRPLANE BEGAN TO DRIFT TO THE LEFT IN GROUND EFFECT, AND SUBSEQUENTLY, IT COLLIDED WITH A FENCE.  A POST-CRASH EXAMINATION REVEALED NO EVIDENCE OF ANY PREEXISTING MECHANICAL MALFUNCTIONS OR FAILURES.

## Factual narrative

On December 31, 1993, at 1130 Pacific standard time, a Grumman AA1B-TR2, N1413R, collided with a fence, and nosed over following a hard landing on runway 24 at Flabob Airport, Riverside, California.  The pilot was conducting a local visual flight rules personal flight.  The airplane, operated by the pilot, was destroyed.  The certificated private pilot and his passenger sustained minor injuries.  Visual meteorological conditions prevailed.  The flight originated at Flabob Airport at 1045 hours.

The pilot stated in the Pilot/Operator Aircraft Accident Report, NTSB Form 6120.1/2, that he used an approach speed of 72 miles per hour and bounced on the initial touchdown.  He applied power and right rudder, but bounced again.  The right rudder application was ineffective.  On the second touchdown, the airplane veered to the left, exited the runway, and collided with a fence.

A ground witness reported that he observed the airplane in a 30- degrees nose-up attitude about three feet above the ground.  The airplane "...wobbled..." toward the south and struck a fence.  The airplane then flipped over on its back.

Mr. Daniel W. Allison, Principal Maintenance Inspector, Federal Aviation Administration (FAA), Riverside [California] Flight Standards District Office, conducted the on-scene investigation.  Inspector Allison reported that the airplane struck the fence during a go-around while in ground effect.

Inspector Allison also said that he examined the engine and found no evidence of any preexisting malfunctions or failures.
