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.

Iaw: 8900.1VOL 7 ch 1 sec 1

Description of the deviation:

On may 4, 2024, the privacy data omitted of a vans RV-8, registration privacy data omitted, was practicing short field landings at an unapproved grass strip on the privacy data omittedproperty, where the airplane was hangard. While practicing the landing procedure, the aircraft dipped on its nose, resulting in the aircraft flipping on its back. The pilot was unhurt but the aircraft received substantial damage.

Causual and/or contributing factors:

The landing was uneventful and as the airplane continued to decelerate, the pilot relaxed the back pressure on the controls and applied what was believed to be normal braking. In doing so, potentially the loss of elevator control effectiveness, the elevator could not counter the tail lifting. This caused the nose to dip, striking the prop with the airplane continuing to roll on to its back. The pilot was accustomed to having additional weight in the back as ballast if a passenger was not on board, but this flight there was no passenger or added ballast. As in past flights, this additional weight in the back, help to keep the tail down on landing roll.

Action take to correct prbolemand prvent reoccurance:

Compliance action- couseling

In accordance with the federal aviation administration’s compliance philosophy, you have been counseled on situational awareness, and the importance of the risks associated with the basic transition to tailwheel steering. Ref: FAA-H-8083-3C, CH14. Your willingness to own the situation, share your story with others, and develop processes with an emphasis on the critical points of aerodynamics during the transition to tail wheel steering is commendable. This displays your commitment to aviation safety.

As the FAA filed it

IAW: 8900.1VOL 7 CH 1 SEC 1

DESCRIPTION OF THE DEVIATION:

ON MAY 4, 2024, THE ^PRIVACY DATA OMITTED^ OF A VANS RV-8, REGISTRATION ^PRIVACY DATA OMITTED^, WAS PRACTICING SHORT FIELD LANDINGS AT AN UNAPPROVED GRASS STRIP ON THE ^PRIVACY DATA OMITTED^PROPERTY, WHERE THE AIRPLANE WAS HANGARD. WHILE PRACTICING THE LANDING PROCEDURE, THE AIRCRAFT DIPPED ON ITS NOSE, RESULTING IN THE AIRCRAFT FLIPPING ON ITS BACK. THE PILOT WAS UNHURT BUT THE AIRCRAFT RECEIVED SUBSTANTIAL DAMAGE.

CAUSUAL AND/OR CONTRIBUTING FACTORS:

THE LANDING WAS UNEVENTFUL AND AS THE AIRPLANE CONTINUED TO DECELERATE, THE PILOT RELAXED THE BACK PRESSURE ON THE CONTROLS AND APPLIED WHAT WAS BELIEVED TO BE NORMAL BRAKING. IN DOING SO, POTENTIALLY THE LOSS OF ELEVATOR CONTROL EFFECTIVENESS, THE ELEVATOR COULD NOT COUNTER THE TAIL LIFTING. THIS CAUSED THE NOSE TO DIP, STRIKING THE PROP WITH THE AIRPLANE CONTINUING TO ROLL ON TO ITS BACK. THE PILOT WAS ACCUSTOMED TO HAVING ADDITIONAL WEIGHT IN THE BACK AS BALLAST IF A PASSENGER WAS NOT ON BOARD, BUT THIS FLIGHT THERE WAS NO PASSENGER OR ADDED BALLAST. AS IN PAST FLIGHTS, THIS ADDITIONAL WEIGHT IN THE BACK, HELP TO KEEP THE TAIL DOWN ON LANDING ROLL.

NO ATC ACTIONS CONTRIBUTORY TO THE EVENT.

ACTION TAKE TO CORRECT PRBOLEMAND PRVENT REOCCURANCE:

COMPLIANCE ACTION- COUSELING

IN ACCORDANCE WITH THE FEDERAL AVIATION ADMINISTRATION’S COMPLIANCE PHILOSOPHY, YOU HAVE BEEN COUNSELED ON SITUATIONAL AWARENESS, AND THE IMPORTANCE OF THE RISKS ASSOCIATED WITH THE BASIC TRANSITION TO TAILWHEEL STEERING. REF: FAA-H-8083-3C, CH14. YOUR WILLINGNESS TO OWN THE SITUATION, SHARE YOUR STORY WITH OTHERS, AND DEVELOP PROCESSES WITH AN EMPHASIS ON THE CRITICAL POINTS OF AERODYNAMICS DURING THE TRANSITION TO TAIL WHEEL STEERING IS COMMENDABLE. THIS DISPLAYS YOUR COMMITMENT TO AVIATION SAFETY.
