N118TCostruzioni Aeronautiche Tecna P2010 · 2021

On October 17, 2023, at 1050 eastern daylight time, a Tecnam P2010, N118T, was substantially damaged when it was involved in an accident at Ocala International Airport-Jim Taylor Field (OCF), Ocala, Florida. The flight instructor and the private pilot were seriously injured. The airplane was operated as a Title 14 Code of Federal Regulations Part 91 instructional flight.

Shortly after arrival in OCF following an uneventful cross-country flight, the pilots fueled the airplane with about 27 gallons of fuel before preparing for their return flight to Lakeland Linder International Airport (LAL) Lakeland, Florida. According to the private pilot who was undergoing instrument instruction, they taxied to runway 36 (which was 7,467 ft-long), held short of the runway, and performed an engine run-up on the taxiway. All indications were normal as the engine operated for about 10 minutes while they awaited their takeoff clearance. The controller cleared the pilot for a full-length departure with a right downwind departure to the south.

During the initial takeoff climb, as the airplane reached 300 to 400 ft agl, the engine suddenly “quit.” The loss of engine power was not preceded by any abnormal engine indications. The flight instructor reported that she immediately took control of the airplane and attempted a forced landing straight ahead in the grass northeast of runway 36. The airplane was descending quickly and when the instructor attempted to flare for landing, the airplane did not respond. Neither pilot recalled hearing the stall warning horn.

Witnesses observed the airplane during the climb and reported that after the loss of power the airplane appeared to be going slow and not climbing, with one witness stating that the pilot did “not lower the nose.” During the attempted landing, the witnesses further stated they did not hear the engine operating, and the airplane appeared to bank left immediately before impact. Security camera footage showed the airplane descending in a wings-level attitude and, immediately before impact, the left wing dropped. The airplane impacted the terrain in a left-wing-low, nose-down attitude and skidded to a stop. The instructor stated she did not apply a left control input during short final and did not remember the airplane turning left before impact. The airplane’s stall speed with flaps in the stowed and takeoff position was 59 kts and 53 kts respectively.

Postaccident examination of the wreckage by an FAA inspector revealed substantial damage to the airframe; both wings were deformed downwards at the wing root, and the forward fuselage was crushed. Damage to the engine compartment prevented a detailed examination of the engine at the accident scene. About 55 gallons of aviation fuel was recovered from the airplane. The cockpit flap toggle switch mount was damaged but appeared to be in the UP (retracted) position. The flaps and actuators were substantially damaged during impact.

A subsequent examination was conducted at the aircraft salvage facility four months later. Crankshaft and valvetrain continuity were confirmed throughout the engine and through the rear accessory case by rotating the propeller. The fuel selector was clear and functioned normally, and the fuel filter was clean. The fuel filter housing was full of aviation fuel. The spark plugs displayed normal coloration and normal electrodes as compared to the Champion Aerospace AV-27 Check-A-Plug chart.

The magnetos were removed, and an electric drill was used to spin the input driveshafts. No spark was generated on either magneto. After about two minutes of spinning the left magneto at high rpm, the magneto started to intermittently spark and then sparked normally on all leads after that. The right magneto never sparked. Both magnetos were opened for examination and both exhibited corrosion features on the coils and frame.

A review of airframe and engine maintenance records revealed that the left and right magnetos were removed on June 24, 2023, about four months before the accident, and temporarily replaced with overhauled units. The removed magnetos were sent out and underwent a 500-hour inspection, cleaning, repair and successful bench test on July 10, 2023. On October 6, 2023, 11 days before the accident, the temporary magnetos were removed, and the original magnetos were returned to service and placed back on the original airplane.

The maintenance records also revealed that on December 6, 2022, at 1,084.8 hours total time engine the No. 2 cylinder failed a compression check. A subsequent examination and engine run on January 4, 2023, confirmed adequate compression and the engine was signed off as airworthy. Subsequent 400-, 100-, 50- and 25-hr inspections were accomplished from February 16, 2023, at 1,084.8 hours total time through the 500-hour magneto inspection/rocker arm gasket replacements on October 9, 2023, at 1,685.8 hours total engine time.

On October 16, 2023, the day before the accident, a pilot “squawk” was documented stating that the engine gas temperature “runs a bit high.” The issue was verified but the airplane was noted as safe to fly.
