HISTORY OF FLIGHT

On December 6, 2008, about 1630 eastern standard time, a Piper PA-44-180, N118TP, and a Cessna 172R, N369ES, collided in midair about 18 miles west of the Ft. Lauderdale Hollywood International Airport (FLL), Ft. Lauderdale, Florida. N118TP was owned by Airline Transport Professionals Corp of USA and was being operated under visual flight rules (VFR) as an instructional flight. N369ES was owned by Pelican Flight School and was being operated as a VFR instructional flight. Both airplanes were substantially damaged. The certified flight instructor (CFI) and the certificated commercial pilot aboard N118TP were both killed. The certified flight instructor and the certificated private pilot aboard N369ES were also killed. Both airplanes were operated under Title 14 Code of Federal Regulations (CFR) Part 91. Visual meteorological conditions prevailed at the time of the accident.

Both airplanes were operating in the A-291B concentrated flight training area prior to the time of the accident. This area is depicted on the Miami sectional chart as (A- Alert) special use airspace. A-291B is in operation from 0600 to 2400. The flight altitude for this area is 0 to 3900 feet above ground level (agl), and there is no air to ground communications provided in this area.

According to the owner of Pelican Flight School, the purpose of the Cessna's flight was to practice flight maneuvers prior to the private pilot taking his instrument checkride. Other instructors at the school stated that they heard their flight instructor in the concentrated flight training area A-291B, over frequency 123.45 making position reports. This is a frequency used by the flight schools in the local area when operating in A-291B; flight instructors often use this training area for students. They recalled that the Cessna's pilot reported that he was "North Perry training area, this is a Cessna 172 holding at FRDDY at 2000 feet." No other radio transmissions were heard from the Cessna.

According to the Airline Transport Pilot flight school personnel, the purpose of the Piper's training flight was to train the commercial rated pilot for his multiengine instructor certificate. Based on a report from the Airline Transport Pilot flight school, the airplane departed FLL to conduct a local training flight. There have been no reports of any radio transmissions from the Piper, while in the training area A-291B. According to instructors at the Airline Transport Pilot flight school they were familiar with the 123.45 frequency.

Radar information provided by Federal Aviation Administration (FAA) Air Traffic Control (ATC) personnel indicates that the Cessna was on a 210-degree course magnetic, and was tracking at a speed of 86 knots. The Piper was on a course of 160 degrees magnetic, and was tracking at a speed of 126 knots. Both airplanes converged on the same position, and the collision occurred at about 2,000 feet above ground level (agl), north of the FRDDY intersection.
