A Cessna 152 (C-152)and a Cessna 172 (C-172) collided in mid air while in a closed traffic pattern at Gillepsie Field. A student and flight instructor were aboard the C-152, and a student pilot was the sole occupant of the C-172. The C-172 was cleared to takeoff with instructions to follow the C-152. A third aircraft was also in the traffic pattern at the time. After takeoff, the air traffic controller looked away to check on other traffic but when he looked back, neither aircraft was visible. He made several unsuccessful calls to both the pilots. The student in the C-152 reported that he had turned crosswind as he came abeam of the third aircraft. When he reached pattern altitude, he began his downwind turn. He was trimming the aircraft when he saw the C-172 approaching his position. He banked hard to avoid the aircraft, but felt an impact. The instructor attempted to take the controls and, with both pilots on the controls, they executed an emergency forced landing on a surface street. The aircraft elevator control lost effectiveness and the aircraft landed hard. They did not report any other mechanical abnormalities before or after the collision. Witnesses reported that both aircraft were on a converging flight path. The student pilot in the C-172 was making his second solo flight but had not advised the controller. The controller did not specify that he was number 3 in the pattern. Haze was reported in all quadrants. The Brite radar repeater in the tower cab is not capable of monitoring traffic on the south side of the airport due to terrain height.

History of flight

On November 25, 1997, at 1132 hours Pacific standard time, a Cessna 152, N757FT, collided in-flight with a Cessna 172M, N9518H, while in the traffic pattern at El Cajon, California. Both aircraft were destroyed. The flight instructor and student pilot in N757FT received minor injuries; however, the solo student pilot in N9518H received fatal injuries. The Cessna 152 was being operated as an instructional flight by the Golden State Flying Club. Anglo-American Aviation, Inc was also operating the Cessna 172M as an instructional flight. Both flights originated from Gillespie Field, El Cajon, on the morning of the accident. Visual meteorological conditions prevailed at the time and no flight plans were filed.

The ATCT controller at Gillespie Field reported that he had cleared the pilot of N9518H to takeoff. The clearance was for closed traffic on runway 27L with instructions to follow the Cessna ahead in the pattern (N757FT), which was already upwind on a touch-and-go landing. The student pilot in N9518H acknowledged the clearance and initiated his takeoff. At this time, a third aircraft, which was ahead of N757FT, was also in the traffic pattern. After N9518H took off, the controller looked away to check on the position of traffic approaching from the east. When he looked back, however, neither N757FT nor N9518H were visible. He made several calls to both the pilots of aircraft but neither responded.

The student pilot in N757FT reported that he made a crosswind turn as he came abeam of his downwind traffic. He had climbed to 1,200 feet msl when he began a turn to downwind. He had started trimming the aircraft for level flight when he saw another aircraft, about 20 yards away, headed toward him from his 10 o'clock position. He banked hard to the right to avoid the aircraft, but subsequently felt an impact.

The instructor attempted to take the controls and, with both pilots on the controls, they executed an emergency forced landing on a surface street. The aircraft elevator control lost effectiveness and the aircraft landed hard. They did not report any other mechanical abnormalities before or after the collision.

The tail section of the solo student's aircraft separated in the air. The aircraft struck the roof of a private home while the tail section came to rest in the driveway of another home.

Witnesses reported that the "white" plane (N9158H) was southbound, while the "yellow" (N757FT) plane was in a turn from south to east. About the time the yellow plane had turned 90 degrees, their flight paths converged. It appeared that both aircraft made abrupt maneuvers before the collision. After contact, both aircraft entered steep descents and disappeared from view.

Personnel information

The flight instructor had been employed by the operator to provide dual instruction in the same make and model as the accident aircraft. She had logged 154 hours in the preceding 90 days. She had received her airplane single engine instructor rating on December 5, 1996. She was employed by Golden State Flying as a flight instructor, and was giving dual instruction at the time of the accident.

Her student, who was on the controls at the time, was reviewing the flight maneuvers in preparation for his private pilot check ride. He was also endorsed for solo flight and was current in the aircraft.

The solo student pilot was on his second solo flight. He had previously logged .3 hours during his first solo on November 20, 1997. His last dual flight was on the day of the accident. This solo flight was scheduled, but was not supervised.

The student pilot's license had been endorsed for solo in a Cessna 172 by his instructor, but there was no corresponding endorsement in his pilot logbook. His logbook reflected required pre-solo dual flight instruction. His instructor reported that he was an above average student and had had no particular problems thus far in his flying program.

Aircraft information

FAA airworthiness inspectors conducted a review of the aircraft and engine logbooks from both aircraft. The logbook entries indicated that both aircraft had been inspected and maintained in accordance with applicable Federal Air Regulations (FARs).

Meteorological information

The current weather information being broadcast as "information Sierra" on the ATIS frequency was: winds calm; visibility 25 statute miles; haze all quadrants; temperature 23 degrees centigrade; and altimeter setting 30.01 inches of mercury. This was essentially consistent with the conditions reported in the hourly surface weather observation.

Communications

The pilots in both aircraft were in two-way radio contact with the Gillespie ATCT at the time of the accident. The controller advised the pilot of N9518H to "follow the Cessna ahead of you in the pattern" at the time he was cleared to takeoff. The pilot acknowledged the transmission. The controller did not specify that he was number 3 in the pattern. The solo student did not advise the controller that this was his second solo flight.

Airport information

The antennae for the Brite radar repeater in the tower cab at Gillespie Field is located at Miramar Naval Air Station and, due to terrain height, is not capable of monitoring traffic on the south side of the airport. It does become available to monitor traffic in that area when the aircraft are at least 1,600 to 2,000 feet msl. The pattern altitude for runway 27L is 1,200 feet msl.

Wreckage and impact information

The wreckage of N757FT was located at 32 degrees 48.8 minutes north longitude and 117 degrees 00.1 minutes west latitude, approximately 1,600 feet south of Valley Lake. The bearing from Gillespie Field was 229 degrees and it was located 1.8 statute miles from the center of the airport.

The aircraft made a forced landing, traveling diagonally across the roadway in a southwesterly direction. The aircraft crossed the center divider, two lanes of opposing traffic, and struck a frangible based aluminum light pole with its right wing. It then yawed right, crossed the curb, and went partially through a 6-foot chain link fence. The nose of the aircraft came to rest extending across a cement lined drainage ditch.

The right main wheel was separated from the strut. The fuselage was partially separated at the control panel and was also buckled downward aft of the luggage area.

A further examination of N757FT revealed trailing edge damage to the left wing and a series of slashes in the leading edge of the left horizontal stabilizer. In the area of the slashes, the metal was extruded from the upper skin surface toward the bottom side of the stabilizer. The distance between the slashes was 5.5 inches, 5.5 inches, 5 inches, and 2.5 inches, measured inboard along the leading edge.

The main wreckage of N9518H was located at 32 degrees 49.1 minutes north longitude and 116 degrees 59.7 minutes west latitude. The bearing from Gillespie Field was 233 degrees and was located 1.4 statute miles from the center of the airport.

The aircraft struck the roof of a home, coming to rest near the rear of the house next to the kitchen. The fuselage separated at the firewall with the forward portion coming to rest on the dining room floor. The nose gear, engine cowling, and remains of the instrument panel were found embedded in the roof. The cabin, forward section of the empennage, wings, and main landing gear came to rest in an inverted position on the rear patio.

Fuel from the aircraft was reported by El Cajon firefighters to have pooled on the patio and in the kitchen of the house.

A further examination of N9518H revealed that the empennage had separated from the aircraft before impact. An imprint with the letters "NE" visible was found on the right side of the empennage of N9518H. The tire on the left main gear of N757FT had the words "AERO TRAINER" on the sidewall. The separa
