(-23) On April 27, 2003 at approximately 2205 pacific daylight time a Beech 35, registration number N9640Y, registered to Mr. Dennis r. campbell landed gear up on runway 34L at Paine field (pae) located in Everett, WA. This incident occurred while Mr. Campbell was conducting a title 14 CFR part 91 pilot proficiency flight, no flight plan was filed. Visual meteorological conditions existed at the time of the incident. The aircraft sustained minor damage. The sole occupant of the aircraft, Mr. Campbell was not injured. Mr. Campbell stated that he had completed three takeoffs and landings without incident. As he commenced the fourth takeoff he stated that he noticed flashing lights off the left side of the runway. During climb out Mr. Campbell states he received a radio transmission from an airport security vehicle indicating that runway 34L would be closed for a runway debris sweep. Mr. Campbell turned to enter a right downwind and stated he observed flashing lights on the runway. He stated that he considered extending his downwind but instead slowed the aircraft. He continued to observe the vehicles on the runway and while still on downwind received a radio transmission indicating that the sweep crew had cleared the runway and the runway was open. He turned base to final. Mr. Campbell stated that he noticed that the manifold pressure indication was slightly lower than normal at approach speed. He indicated that he used the VASI to establish his glide path and was intent on greasing the landing. Mr. Campbell states that he normally uses a checklist for all phases of flight; however, the distraction created by the runway closure and monitoring vehicles on the runway diverted his attention causing him to mismanage the landing gear control. Mr. Campbell states that he did not hear a landing gear warning horn. FAA records show that Mr. Campbell holds a private pilot certificate with airplane single engine land and instrument ratings. The certificate was last issued on March 22, 1999. Mr. Campbell holds a third class medical certificate issued on November 22, 2002; the certificate is clear with no restrictions. Mr. Campbell has 920 hours total time, 771 hours in type and 8 hours in the last ninety days. Mr. Campbell completed his last regulatory check ride on April 15, 2003. Mr. Campbell states he takes aspirin and lipitol at a physician direction to control cholesterol. He also stated that he takes melatonin as a sleep aid. Mr. Campbell stated that he had not taken any of these drugs prior to the incident flight. The airplane is a Beech p 35, serial number D-7085 manufactured in 1962. FAA records indicate this aircraft has no previous accident/incident history. Maintenance records indicate that the aircraft underwent an annual inspection and was found airworthy on November 8, 2002. The aircraft operated 11 hours since the last annual inspection. The total time on the aircraft is 4267 hours. After the incident the aircraft was to move to a repair facility. A functional test of the landing gear extension/retraction/indication and warning system was performed. The test indicates that the landing gear system, its indication and warning system functions normally. It is noted that although the landing gear warning horn sounds with the landing gear up and the throttle retarded the manifold pressure setting is unknown. The FAA placed a request with the repair facility to measure and record the throttle position required to activate the landing gear warning horn (current condition) and measure the position again upon completion of repair and functional check to include a flight. The aircraft engine suffered a sudden stoppage. Both propeller blades were curled back. The left hand and right hand flaps were wrinkled at the inboard aft corner. The left hand and right hand nose landing gear doors had abrasion damage, as did the belly skin surrounding the nose wheel well. A belly mounted adf antenna was damaged. Weight and balance was not a factor. Meteorological conditions at the time of the incident were not a factor. The Paine field weather was as follows: METAR kpae 280453Z 36005KT 10SM clr 10/06 A2993.
