N63CA

HISTORY OF FLIGHTOn March 15, 2013, about 1621 eastern daylight time, a Piper PA-31T (Cheyenne), N63CA, owned by M.A.S. Inc., was destroyed after it impacted the ground shortly after takeoff from the Fort Lauderdale Executive Airport (FXE), Fort Lauderdale, Florida. The airline transport pilot and two passengers were fatally injured. Visual meteorological conditions prevailed and no flight plan had been filed for the local maintenance test flight that was conducted under the provisions of 14 Code of Federal Regulations Part 91.

According to information obtained from the Federal Aviation Administration (FAA), and personnel interviews, the airplane was purchased by its current owner during November 2012, for a third party in Columbia, and was being prepared for export. The pilot planned to conduct a local test flight after avionics upgrades had been performed. The passengers were a father and son, who both worked at the company that performed the avionics upgrades.

Another pilot reported that he was asked by one of the passengers to conduct a test flight in the airplane 2 days before the accident. The pilot stated that he did not have time to conduct a test flight; however, he sat in the cockpit during a ground check of the right engine to troubleshoot a faulty oil temperature gauge. The engine performed normally, with the exception of the oil temperature gauge reading below zero. In addition, a functional check of the avionics was performed with no discrepancies noted.

The owner reported that the airplane had undergone engine ground checks during the 4 days prior to the accident. He was not aware of any maintenance issues with the airframe or engines, which underwent detailed inspections at the time of the purchase.

The airplane departed from runway 8, a 6,002-foot-long, asphalt runway, and was expected to turn to the left for a northwest departure. Shortly after takeoff, witnesses observed the airplane make a steep right turn back toward the airport. The pilot transmitted that he was experiencing an "emergency;" however, he did not state the nature of the emergency prior to the accident. One witness, who was a pilot in an airplane that was parked in the mid-field run-up area at FXE, stated that the accident airplane had difficulty climbing and barely cleared the obstacles located off the departure end of the runway. The airplane turned to the right, and "began to shake as if it was near stall speed." The airplane then appeared to stall, roll to the right about 90 degrees, and descend straight down toward the ground. Nearby surveillance video depicted the airplane entering a right roll that was at or about 90 degrees before it descended out of camera view.

Radar data obtained from the FAA depicted a target consistent with the airplane at an altitude about 100 feet mean sea level (msl), about 3,600 feet from the beginning of runway 8, about 200 feet off the right side of the runway. The radar target continued to drift to the right, and reached a maximum ground speed about 110 knots, and a maximum altitude about 300 feet. The target then entered a progressively steepening right bank, and slowed to a ground speed about 90 knots before radar contact was lost about 800 feet east-northeast of the accident site. PERSONNEL INFORMATIONThe pilot, age 65, held an airline transport pilot certificate, with ratings for airplane single-engine land, airplane multiengine land, and instrument airplane. He also held a flight instructor certificate with ratings for airplane single-engine land, airplane multiengine land and instrument airplane. The pilot also held type ratings for HS-125, CE-500, CE-650, CL-600, DA-200, G-1159 and Lear Jet series airplanes.

His most recent FAA first-class medical certificate was issued on May 7, 2012. At that time, he reported a total flight experience of "10,000+" hours, which included 95 hours during the previous 6 months.

The pilot's current logbook was not located. According to an FAA inspector, the accident pilot regularly flew several types of airplanes, including the Piper PA-31 series airplanes. Logbook excerpts current as of June 13, 2012, revealed about 70 hours logged since January 1, 2012, which included 12 hours in PA-31 series airplanes. AIRCRAFT INFORMATIONThe twin-engine, retractable-gear, low wing, all metal turbine powered airplane, serial number 31T-7820033, was manufactured in 1978. It was powered by two Pratt & Whitney Canada PT6A-28, 680-horsepower engines, equipped with three-bladed Hartzell constant-speed propeller assemblies.

The airplane was equipped with a Stability Augmentation System (SAS) designed to automatically improve the static longitudinal stability of the airplane by providing variable elevator force. This was accomplished through tension changes in an elevator down spring. An angle of attack sensing vane located on the right side of the fuselage nose section signals the SAS computer, which powers the elevator down spring servo. Other functions of the SAS computer are activation of the stall warning horn and providing the signal for the visual stall margin indicator on the upper left side of the instrument panel. The stall margin indicator receives its signal from the angle-of-attach vane through the conditioning computer and presents a visual indication of the ratio of present speed to the stall speed in the same configuration.

According to the airplane Pilot Operating Handbook, the listed Air Minimum Control Speed (Vmca), which was the lowest airspeed at which the airplane is controllable with one engine operating and no flaps was an indicated airspeed of 91 knots. The single engine best rate of climb speed was 113 knots.

The airplane was equipped with four interconnected fuel tanks in each wing, in addition to a respective wingtip fuel tank. The right and left wing fuel systems were independent of each other and fuel was supplied to the engines by its respective inboard fuel cell. The total fuel system capacity was 374 gallons. According to fueling records, the airplane was refueled 51 gallons of Jet-A fuel prior to the accident flight. A line serviceman reported that approximately 25 gallons of fuel was added to the left and right wingtip fuel tanks. The total amount of fuel onboard the airplane at the time of the accident could not be determined.

At the time of the accident, the airplane had been operated for about 5,030 total hours, which included about 25 hours since its most recent documented phase inspections, which were performed on January 31, 2012. The airplane was operated for about 12 total hours during 2011.

In addition, at the time of the accident, the right and left engines had been operated for about 1,430 hours since they were overhauled during November 2000. The right propeller had been operated for about 3 hours since it was installed after overhaul during November 2012, and the left propeller had been operated for about 135 hours since it was installed after overhaul during November 2008.

The registered owner reported that the airplane had flown about 3 additional hours in November, after the airplane was delivered from Sarasota, Florida, to FXE.

Review of maintenance records did not reveal a current annual inspection for the airplane.

An airframe and powerplant mechanic reported that he was hired by one of the passengers to conduct a 100 hour inspection of the airplane, which he worked on during the month prior to the accident, but was not completed due to the avionics work that was being performed at the time. He further stated that the airplane still required a landing gear swing, weight and balance check, and a flight control system check before the inspection could be completed and logged. The mechanic was not provided any "squawks" and was not aware of an issue with the right engine oil temperature gauge. METEOROLOGICAL INFORMATIONThe reported weather at FXE, elevation 13 feet, at 1639, was: wind 060 degrees at 7 knots, visibility 10 statute miles; scattered clouds at 4,000 feet; temperature 21 degrees Celsius (C); dew point 8 degrees C; altimeter 30.16 inches of mercury.
