N4008F

HISTORY OF FLIGHT

On May 2, 2008, about 1950 mountain daylight time, a Cessna 172N, N75856, and a Cessna 172, N4008F, collided in-flight over the approach end of runway 34 at the McCall Municipal Airport (uncontrolled), McCall, Idaho. Both airplanes were destroyed during the collision sequence and postcrash fire that ensued. N75856's commercial pilot received serious injuries; the passenger sustained minor injuries. Of the four occupants aboard N4008F, the private pilot and two passengers were killed; the third passenger received serious injuries. N75856 was operated by Felts Field Aviation under the provisions of Title 14 Code of Federal Regulation (CFR) Part 91. The visual flight rules (VFR) personal cross-country flight originated from Felts Field Airport in Spokane, Washington, approximately 1 hour and 30 minutes prior to the accident. A VFR flight plan was in effect. N4008F was operated by the owner/pilot under the provisions of Title 14 CFR Part 91. The VFR personal cross-country flight originated from Caldwell Industrial Airport, Caldwell, Idaho, approximately 45 minutes prior to the accident and was returning to McCall where the airplane was based. No flight plan was filed. Day visual meteorological conditions prevailed at the time of the accident.

In a written statement, the pilot of N75856 (172N) reported that he entered the downwind leg of the traffic pattern for runway 34 from a 45-degree angle at 6,500 feet mean sea level (msl). He made a radio traffic call as he adjoined the downwind leg, and reduced engine power when the airplane was abeam the runway identifier numbers. He configured the airplane with 10 degrees of flaps prior to turning onto the base leg and again, transmitted his position over the radio. The pilot turned the airplane onto final approach and conveyed his intention to "land long" over the radio. He further stated that while the airplane was approximately 30 feet above the runway surface he maneuvered the airplane into a flare. Immediately thereafter the collision occurred. The pilot reported that he was not aware of his position relative to the other airplane prior to, and during the collision sequence.

During an interview with a Safety Board investigator, a witness on the ground reported that both airplanes appeared to be on final approach for runway 34, with one above the other; he lost sight of them prior to the collision. The witness added that shortly after loosing sight of the airplanes he observed a cloud of black smoke near the approach end of the runway.

The airplanes came to rest on the west shoulder of runway 34 about 1,737 feet north of the landing threshold. The airplanes sustained extensive fire and impact related damage.

RADAR INFORMATION

Recorded radar data was obtained from the Salt Lake City Air Route Traffic Control Center (ARTCC) using data from the Fossil, Oregon, air route surveillance radar (ARSR) and the Cascade/Boise, Idaho ARSR. Based on the information obtained from both facilities, two radar tracks were indentified and consistent with the anticipated flight paths of the accident airplanes.

A review of the data disclosed that a primary track (transponder code 1200), consistent with that anticipated for N75856, descended towards the airport from the northwest. The radar return then displayed a turn to the south consistent with adjoining onto the downwind leg for runway 34. At 1949:20 the radar return was approximately midfield, southbound, at 5,800 feet mean sea level (msl). At 1949:58 the radar return tracked east, consistent with a base leg for runway 34, and at 1950:08 the radar return associated with the airplane turned north, consistent with a final approach leg for runway 34, at 5,600 feet msl. The radar return continued in a northbound descent toward the runway.

A review of the data disclosed that a primary track (transponder code 1200), consistent with that anticipated for N4008F, descended towards the airport from the south consistent with a straight-in approach for runway 34. At 1949:58 the radar return was at 5,400 feet msl and continued northbound, consistent with a final approach leg for runway 34. At 1950:08 the radar return was at 5,300 msl. The flight path continued northbound and descended toward the runway.

PERSONNEL INFORMATION

Pilot of N75856

The pilot of N75856, age 30, held a commercial pilot certificate for single-engine land, multi-engine land and instrument airplanes. The pilot held a certified flight instructor certificate (CFI) for single-engine and multi-engine airplanes, and instrument (CFII). The most recent FAA first-class medical certificate was issued to the pilot on July 10, 2007, and contained the limitation that he wear corrective lenses.

The pilot reported that his total aeronautical experience consisted of 478 flight hours; 351 flight hours were accrued in the capacity of pilot- in-command (PIC) and 143 flight hours were obtained in the same make and model as the accident airplane. Approximately 49 hours were accrued during the previous 90 days. The pilot completed a flight review on October 15, 2007.

Pilot of N4008F

The pilot of N4008F, age 52, held a private pilot certificate for single-engine land airplanes. The most recent FAA third-class medical certificate was issued to the pilot on August 29, 2007, and contained the limitation that he must have glasses available for near vision.

No personal flight time records (log books) were located by the Safety Board for the pilot. On an insurance application dated January 28, 2008, the pilot indicated that his total aeronautical experience consisted of 808 flight hours, of which 386 were accrued in the same make and model as the accident airplane. On the application, the pilot indicated that he completed a flight review on February 18, 2008.

AIRCRAFT INFORMATION

N75856

The Cessna 172N was manufactured in 1977. The high-wing single-engine airplane was equipped with a Lycoming engine, model O-360. The airplane was predominately white with orange and brown accent stripes on each side. According to the pilot, the fuel tanks were filled full prior to the departure from Spokane.

N4008F

The Cessna 172 was manufactured in 1958. The high-wing, single-engine airplane was equipped with a Continental engine, model O-300. The airplane was white with a red and blue stripe on the wing tips and a solid blue color undercarriage. According to family members of the pilot, the fuel tanks were filled full prior to the departure from Caldwell.

Neither airplane was equipped with collision avoidance equipment, nor is such equipment required by the Federal Aviation Administration (FAA).

Both airplanes were equipped with two-way radios. The preaccident frequency selection of the radios could not be determined due to thermal and impact related damage.

WRECKAGE AND IMPACT INFORMATION

The airplanes came to rest entangled on the west side of runway 34, about 1,737 feet north of the landing threshold. Both sustained extensive impact and fire related damage. The first identified wreckage debris was located on the runway (near the centerline) approximately 1,000 feet north of the landing threshold. The debris consisted of blue colored paint chips and small pieces of aircraft structure.

N75856:

The wreckage came to rest, upright, on the west side of the runway. Extensive thermal damage was noted to the cockpit, cockpit controls, instrumentation and cabin area. The engine assembly and associated cowling were located adjacent to the main wreckage; the two-bladed propeller (Sensenich) and spinner remained attached to the engine. Leading edge damage and chord wise scratches were noted on both propeller blades. A section of blade tip, measuring approximately 3-inches in length, was separated from one of the propeller blades.

The main landing gear (left and right) was located with the main wreckage and thermal type damage was noted. The nose landing gear was separated from the airframe and located approximately 75 feet south of the main wreckage. Investigators found blue paint transfer and scuffing on the left lower sidewall of the nose wheel tire.

The wings were located amid the main wreckage. Thermal damage was noted to the inboard section, which extended the entire thickness. The right and left lift struts were intact and remained attached to their respective wing assembly. The right wing flap and aileron were attached to the wing structure and nominal damage was noted. Thermal damage was noted to the upper wing skin of the left wing. The outboard section, approximately mid span, of the wing was bent and rolled upward. The left wing flap and aileron were attached to the wing structure. The aileron was bent a...
