Newbolds Corner, NJ, USA
N56885
Piper PA-28-140
The pilot of the Piper PA-28-140 reported that he departed on a cross-country flight with full fuel tanks. After 2 hours and 5 minutes of flight, the engine lost power, and he performed a forced landing to a field. Examination of the airplane revealed no fuel in the tanks, and a fuel stain on the firewall. When fuel was added and the fuel system pressurized, fuel leaked from the b-nut at the exit side of the engine driven fuel pump. The b-nut was able to be tightened two full turns by hand. The engine had recently been removed and replaced, and the fuel sensors in the wings changed. The maintenance was performed at an FAA approved repair station. However, there was no specific requirement for inspection of fuel lines prior to returning the airplane to service. In addition, the pilot reported that he did not believe the accuracy of the fuel gauges.
On February 17, 2002, at 0939 eastern standard time, a Piper PA-28-140, N56885, was substantially damaged during a forced landing near Newbolds Corner, New Jersey. The certificated private pilot and passenger received minor injuries. Visual meteorological conditions prevailed for the personal flight. No flight plan had been filed for the flight that was conducted under 14 CFR Part 91. According to the pilot, the airplane had recently received an annual inspection. The work included removing both fuel tanks to replace the fuel transmitters, the fuel lines, both cockpit fuel gauges, and replacement of a cylinder on the engine. In addition, the engine was removed and replaced to work on the engine mount. The pilot subsequently flew the airplane on February 15, 2002, from Norfolk, Virginia, to Bedford, Massachusetts. At Bedford, the airplane was serviced with 35 gallons of 100 low lead aviation grade gasoline. On February 17, the pilot initiated the return flight. He reported that prior to departure, he had visually checked both fuel tanks, and they were filled to capacity (48 gallons useable). He had planned on an en route stop at Atlantic City (ACY), New Jersey, on the return flight. The pilot reported the flight was without incident until it was south of John F. Kennedy (JFK), at which time, the engine began to run rough. He changed to the left fuel tank and the engine ran smoothly. He also changed his destination from ACY, to Flying W Airport (N14), Lumberton, New Jersey, an airport he was familiar with. The airplane crossed the New Jersey shore line near Colts Neck. After about 15 minutes of running on the left fuel tank, the engine lost power, as if it were out of fuel. The pilot selected right fuel tank and the engine resumed power. At that time the left fuel tank read empty, and the right fuel tank read about 1/3. The pilot continued toward N14. The pilot also reported that he thought the low fuel readings was due to inaccuracies in the system, and not an actual low fuel state. He did not trust the gauges based upon previous experience. About 10-15 minutes later, the engine lost power again, and the pilot was unable to affect a restart. He did not remember looking at the fuel gauges at that time. The pilot reported there was a strong quartering crosswind from 310 degrees as he approach a field for the forced landing. While low over trees, he encountered a wind shear and the airspeed decreased from 71 mph to 60 mph. The airplane was near a stall, and hit on the right main landing gear and right wing first, followed by the left main landing gear and then the nose wheel. The location of the field was about 2 miles north of N14. According to archived weather reports from South Jersey Regional Airport (VAY), Medford, New Jersey, which was about 3 miles southwest of the accident site, at 0954, the winds were from 310 degrees at 8 knots with gusts to 15 knots, and at 1054, they were from 310 degrees at 14 knots, with gusts to 18 knots. According to an inspector from the Federal Aviation Administration (FAA) who examined the airplane, the left main landing gear had been driven through the wing, and collapsed rearward and inboard. The nose landing gear was separated from the airplane, and the firewall was wrinkled. The right wing was wrinkled, and bent up outboard of the wing flap. The fuel system was intact; however, no fuel was visible in the fuel tanks, and there was no evidence of fuel staining around the fuel caps, or under the wings. Under FAA supervision, fuel was added to both tanks, and the electric boost pump turned on. Fuel was observed leaking from around the B-nut on the exit side of the engine driven fuel pump, and on the fuel line that connected to the carburetor. A fuel stain was found on the firewall behind the leaking B-nut. The B-nut was found to be finger loose and was tightened two full turns. After tightening, the fuel system was again pressurized and no leaks were observed. The engine was started and ran. High power was not demonstrated due to a bent propeller. Fuel flowed from both fuel tanks to the engine with no leaks or problems reported. In a follow-up telephone interview, the mechanic who conducted the test reported that when electrical power was first turned on, the fuel gauges read empty. After fuel had been added to the fuel tanks, both fuel tank fuel gauges registered a quantity of fuel, when the electrical power was turned on. According to FAA records, the maintenance facility that performed the work carried a 14 CFR Part 145 Repair Station certificate, with class 3 airframe and limited powerplant ratings. According to the maintenance supervisor from the FAA Flight Standards District Office (FSDO) that supervised the repair station certificate, the work performed was within the scope of the repair station certificate. Although the facility employed both maintenance personnel and inspectors, there was no specific requirement for the work to be viewed by an inspector prior to being returned to service. According to the chief inspector from the maintenance facility that had performed the work on the airplane, there was no specific requirement for the work to be viewed by an inspector prior to returning the airplane to service. However, the airplane would have received an inspection overview. In addition, the airplane had accumulated about 6 hours between ground runs, and maintenance flight checks, after the engine was replaced. Further, the fuel line was not required to be secured with safety wire, and none had been used. The maintenance facility did not have a procedure in place to mark an inspected fitting with torque seal, or some other type of marking to indicate that it had been inspected.
Improper maintenance which resulted in a loss of fuel and subsequent loss of engine power due to fuel exhaustion. Factors were the pilot's failure to monitor the fuel quantity gauges, and the gusty wind conditions.
