N9941M

HISTORY OF FLIGHT

On January 9, 2007, about 1035 Alaska Standard time, a wheel-equipped Cessna 207A airplane, N9941M, sustained substantial damage when it ditched in the ocean waters of the Cook Inlet during an emergency forced landing, about 18 miles west of Kenai, Alaska. The airplane was being operated as a visual flight rules (VFR) cross-country nonscheduled cargo flight under Title 14, CFR Part 135, when the accident occurred. The airplane was operated by Air Supply Alaska Inc., Kenai. The commercial certificated pilot, the sole occupant, was not located at the accident scene, and is presumed to have received fatal injuries. At the time of the accident, visual meteorological conditions prevailed over the Cook Inlet. As search operations progressed, the weather conditions deteriorated, and instrument meteorological conditions prevailed over the inlet. VFR company flight following procedures were in effect. The flight originated at the Kenai Airport about 1023, and was en route to Kokhanok, Alaska.

The company director of operations/owner reported that the pilot began the day by preparing for the accident flight. This included preflight and engine start. The airplane had been parked on the airport ramp overnight, with an electric engine heater plugged in, and an engine cover installed. After engine start, the pilot contacted the Federal Aviation Administration (FAA) air traffic control personnel at the Kenai air traffic control tower (ATCT) and said that he was taxiing for takeoff. He then returned to the company ramp, shut down the engine, and contacted the company owner. The pilot indicated that the engine oil pressure appeared to be lower than normal, but still in the operating range. The owner indicated that he and the accident pilot discussed the possible reasons, such as cold ambient temperatures. The owner said the pilot indicated he would monitor the oil pressure prior to crossing the Cook Inlet, en route to Kokhanok.

At 1020, the pilot again contacted the Kenai ATCT, and said that he was taxiing for takeoff. At 1022, the pilot advised he was ready for departure, and was cleared for takeoff at 1023. After departure, he contacted a company employee on the company radio and advised that his departure time was 1025, and his flight time was anticipated to be 1 hour and 15 minutes. The pilot also reported that he intended to "go down" from his normal crossing point across the Cook inlet, and indicated that the engine pressure was "up in the green and good to go."

At 1033:54, the pilot contacted Kenai tower and stated, "Yes, I have a mayday. I've, ah, substantial vibration has occurred, ah, I can't see, ah, problem, I'm mid-channel, descending." The Kenai tower controller asked for the pilot's position, and the pilot said, "I'm mid-channel headed for the (unintelligible.) At 1035:06, the pilot stated, "I'm headed into the water, 60:40.94 [degrees north latitude] 151:43.542 [degrees west longitude], Mayday, Mayday." No further communication was received from the pilot.

The operator's director of operations was preparing to depart Kenai in another company airplane, and he monitored the mayday call. He asked about the accident location, departed from Kenai at 1039, and headed toward the area of the accident. Kenai ATCT personnel indicated that there was a possible radar target approximately 12 miles northwest of Kenai. That location was between Nikiski, Alaska, on the west shore of the Kenai Peninsula, and Redoubt Bay, on the east shore of the Alaska Peninsula.

At 1046, Air Route Traffic Control Center (ARTCC) personnel, Anchorage, Alaska, contacted Kenai tower personnel via telephone, stating, "..I see that, ah, for this downed aircraft is 12 miles northwest of the VOR. Do you have anything better than that." Kenai tower personnel responding by stating, "Really, not at this time. Unofficially, we think we had a target on our radar. We got possible coordinates on him, but we have to check the tapes to make sure." ARTCC personnel inquired about a radial (magnetic direction) from the VOR, and Kenai personnel stated, "A good guess would be looked like the 310 to 330 [radial] off the East Forelands, maybe."

Several aircraft heard the unfolding emergency situation and responded to the area of the crash. The Air Force Rescue Coordination Center (AFRCC) was notified and search personnel were dispatched to the area.

About 1218, an emergency locator transmitter (ELT) signal was detected by U.S. Coast Guard search aircraft. About 1241, the tail of the partially submerged airplane was spotted floating vertically in about 60 feet of water, and the vessel "Sea Bulk Nevada" was directed to the area. The location was about 8.8 miles southwest of the initial accident site reported by the pilot. The 215 foot long vessel recovered the airplane about 1453 from the inlet, which had wide areas of floating ice and ice fog. The airplane was intact, with the exception of the nose wheel assembly, which was missing. A crewmember on the vessel reported that he saw what appeared to be two tire tracks on the pan ice, about 50 to 60 feet long, to the edge of the ice where the airplane was located.

The pilot was not recovered with the airplane, and subsequent searches did not locate him.

PERSONNEL INFORMATION

Pilot Information

The pilot held a commercial pilot certificate with airplane single-engine land, single-engine sea, and instrument airplane ratings. He also held private pilot privileges with a multiengine land rating. The most recent second-class medical certificate was issued to the pilot on April 3, 2006, and contained the limitation that the pilot must wear corrective lenses.

The pilot was hired by the operator on April 8, 2006. He completed his initial ground and flight training on May 5, 2006. He took a CFR Part 135.293 and Part 135.299 airman competency/proficiency flight check with an FAA inspector from the Anchorage Flight Standards District Office (FSDO), Anchorage, Alaska, on May 4, 2006. The inspector indicated that the result of the flight check was unsatisfactory in emergency procedures and judgment, and disapproved the checkride. The following day, after another flight check, the inspector approved the pilot.

No personal flight records were located for the pilot, and the aeronautical experience listed on page 3 of this report was obtained from the operator's records, and from an insurance company application completed by the pilot. The operator indicated that the pilot's total aeronautical experience consisted of about 5,291 hours, of which 512 hours were accrued in the accident airplane make and model.
