What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
Description: on 1/2/2018 at approximately 18:35, N33296 landed at the Scappoose Industrial Airpark (ksbp) with the landing gear retracted.
The pilot of N33296 was conducting a night currency flight to meet the requirements of 14 CFR part 91.57(b)(1). On the last trip around the traffic pattern, the pilot of N33296 engaged in a conversation over the radio with the pilot of another aircraft. The conversation distracted the pilot of N33296 and he failed to extend the landing gear prior to landing. The aircraft came to a stop on the runway with minor damage to the underside of the aircraft and all three propeller blade tips bend backwards.
Causal or contributing factors: the distraction of the pilot from operating the aircraft in accordance with the pilot?s operating handbook is the primary causal factor. With the aircraft on jacks and the landing gear system tested, it was determined by maintenance personnel that the landing gear warning system did not provide an intermittent audible tone when the throttle was moved to a position that would be representative of less than 12 inches of manifold pressure.
The system was inoperative due to excessive wear on a cam on the throttle linkage that contacts a roller switch to activate the audible warning tone if the landing gear is not down and locked. Other than the lack of the audible tone, the landing gear functioned appropriately.
As the FAA filed it
DESCRIPTION: ON 1/2/2018 AT APPROXIMATELY 18:35, N33296 LANDED AT THE SCAPPOOSE INDUSTRIAL AIRPARK (KSBP) WITH THE LANDING GEAR RETRACTED.
THE PILOT OF N33296 WAS CONDUCTING A NIGHT CURRENCY FLIGHT TO MEET THE REQUIREMENTS OF 14 CFR PART 91.57(B)(1). ON THE LAST TRIP AROUND THE TRAFFIC PATTERN, THE PILOT OF N33296 ENGAGED IN A CONVERSATION OVER THE RADIO WITH THE PILOT OF ANOTHER AIRCRAFT. THE CONVERSATION DISTRACTED THE PILOT OF N33296 AND HE FAILED TO EXTEND THE LANDING GEAR PRIOR TO LANDING. THE AIRCRAFT CAME TO A STOP ON THE RUNWAY WITH MINOR DAMAGE TO THE UNDERSIDE OF THE AIRCRAFT AND ALL THREE PROPELLER BLADE TIPS BEND BACKWARDS.
CAUSAL OR CONTRIBUTING FACTORS: THE DISTRACTION OF THE PILOT FROM OPERATING THE AIRCRAFT IN ACCORDANCE WITH THE PILOT?S OPERATING HANDBOOK IS THE PRIMARY CAUSAL FACTOR. WITH THE AIRCRAFT ON JACKS AND THE LANDING GEAR SYSTEM TESTED, IT WAS DETERMINED BY MAINTENANCE PERSONNEL THAT THE LANDING GEAR WARNING SYSTEM DID NOT PROVIDE AN INTERMITTENT AUDIBLE TONE WHEN THE THROTTLE WAS MOVED TO A POSITION THAT WOULD BE REPRESENTATIVE OF LESS THAN 12 INCHES OF MANIFOLD PRESSURE.
THE SYSTEM WAS INOPERATIVE DUE TO EXCESSIVE WEAR ON A CAM ON THE THROTTLE LINKAGE THAT CONTACTS A ROLLER SWITCH TO ACTIVATE THE AUDIBLE WARNING TONE IF THE LANDING GEAR IS NOT DOWN AND LOCKED. OTHER THAN THE LACK OF THE AUDIBLE TONE, THE LANDING GEAR FUNCTIONED APPROPRIATELY.
