NTSB Factual Report

HISTORY OF FLIGHT

On July 16, 2016, about 1845 eastern daylight time, a Piper PA-28R-201, N2241Q, collided with terrain after takeoff from Hogan Airport (NY05), Esperance, New York. The private pilot was seriously injured, the three passengers were fatally injured, and the airplane was destroyed. No flight plan was filed for the personal flight conducted under the provisions of 14 Code of Federal Regulations Part 91. Visual meteorological conditions prevailed for the flight that originated at NY05 and was destined for Tweed-New Haven Airport (HVN), New Haven, Connecticut.

According to a fixed base operator at HVN, on the day of the accident, the airplane was fueled with 14 gallons of 100LL aviation fuel, which brought the fuel level to "just above the tabs." The pilot then flew the airplane with the three passengers onboard from HVN to NY05. According to witnesses, the pilot and passengers attended a party at NY05. A witness reported that the accident airplane was the last of a group of airplanes to depart from NY05 and that another pilot had suggested to the accident pilot that he depart on runway 12L. A review of surveillance video revealed that the airplane took off on runway 30R, which was 3,000 ft long; the first 600 ft and the final 400 ft of runway 30R were turf, and middle 2,000 ft was asphalt. The surveillance video showed that the pilot began the takeoff roll where the paved section of the runway began (with 2,400 ft of available runway). During the takeoff roll, the nosewheel of the airplane lifted off and then settled back onto the runway. The nosewheel lifted again, and the airplane became airborne with about 900 ft of runway remaining.

Several witnesses observed the airplane's takeoff from runway 30R. They consistently described the airplane's takeoff as "slow" and "sluggish" and reported that it entered a "gentle" left turn immediately after takeoff. One witness stated that the airplane attempted to rotate earlier than the other airplanes that were departing that day. When the airplane became airborne, "the nose was pitched so high that the wings wallowed;" the witness then reached for his phone to dial 911. The airplane overflew a hangar located left of the departure end of the runway at a low altitude as it continued its left turn before descending into trees. Another witness stated that "the airplane was under full power the entire time. The engine did not fail."

Due to his injuries, the pilot was not interviewed. In a written statement, the pilot reported that he had "no personal recollection of the subject flight."

Radar track data obtained from the Federal Aviation Administration (FAA) depicted the airplane in a left turn after takeoff. The airplane climbed to about 100 ft above ground level, and its groundspeed ranged between 58 and 67 knots from takeoff to the final radar target. The radar track ended about 100 ft beyond the departure end of the runway and about 1,000 ft left of the runway centerline.

PERSONNEL INFORMATION

The pilot held a private pilot certificate with ratings for airplane single-engine land and instrument airplane. He was issued a third-class medical certificate on May 1, 2015. The pilot reported about 561 total hours of flight experience. The pilot's logbooks were not recovered and no determination could be made of his flight experience in the accident airplane make and model.

AIRCRAFT INFORMATION

The four-seat, low-wing, retractable-gear airplane was manufactured in 1977. It was powered by a 200-horsepower Lycoming IO-360 engine driving a McCauley two-blade, constant-speed propeller.

The airplane's most recent annual inspection was completed on March 1, 2016, at 6,573.6 total aircraft hours.

The airplane's weight and balance condition at the time of takeoff was calculated based on the estimated fuel onboard the airplane and the estimated weights of the passengers. According to the information provided by the fixed base operator at HVN, the airplane departed HVN with about 25 gallons or about 300 lbs of usable fuel. Fuel burn from HVN to NY05 was estimated to be about 8 gallons or 48 lbs.

The airplane's takeoff weight at NY05 was calculated to be 2,816.5 lbs, which was 66.5 lbs above the maximum allowable gross weight of 2,750 lbs. There are no performance charts for any weight above the maximum gross weight.

The performance charts indicated that at the airplane's maximum allowable gross weight, the estimated takeoff ground roll was 2,180 ft and the total distance to clear a 50-ft obstacle was 2,750 ft.

According to the pilot's operating handbook for the airplane, the rotation speed for a normal takeoff was between 65 and 75 knots indicated airspeed (KIAS). With a flap setting of 25°, the rotation speed for a short-field takeoff was between 50 and 60 KIAS. After liftoff, the pilot was to increase airspeed to 55 to 65 KIAS.

There are no performance charts or procedures for a 10° flap setting during takeoff. The performance charts do not consider the effects of a grass runway surface on takeoff and landing performance.

The gross weight stalling speed with power off and full flaps is 55 KIAS, and, with flaps up, this speed is increased 5 knots. Loss of altitude during stall can be as great as 400 ft depending on configuration and power. The manufacturer did not publish power-on stall speeds for the airplane. The best rate of climb speed at gross weight is 90 KIAS, and the best angle of climb speed is 78 KIAS.

METEOROLOGICAL INFORMATION

At 1851, the weather reported at Albany International Airport (ALB), Albany, New York, located about 23 nautical miles east of the accident site, included wind from 030° at 3 knots, visibility 10 statute miles; few clouds at 5,000 ft, scattered clouds at 11,000 ft, broken clouds at 22,000 ft, overcast at 25,000 ft; temperature 27°C; dew point 16°C; and altimeter 30.04 inches of mercury. The calculated density altitude at NY05 was about 3,000 ft.

The density altitude at HVN when the airplane departed at 1845 was 1,971 ft.

AIRPORT INFORMATION

NY05 was a private-use airport at 1,260 ft elevation, configured with two parallel runways, each of which was 3,000 ft long. Runway 12R/30L was a turf runway, and runway 12L/30R combined both asphalt and turf surfaces.

The elevation of HVN was 12.4 ft. HVN is equipped with two asphalt runways; runway 2/20 is 5600 ft long, and runway 14/32 is 3,626 ft long.

WRECKAGE AND IMPACT INFORMATION

The airplane came to rest in swampy, wooded terrain and was destroyed by impact and postcrash fire. All major components of the airplane were accounted for at the scene. The wreckage path was oriented on a 180° magnetic heading and was 60 ft in length. The main wreckage was oriented on a magnetic heading of 350° and rested upright about 1,400 ft beyond the departure end of the runway and about 700 ft left of the runway's centerline.

The right stabilator and a portion of the right wing were separated and found in trees along the debris path. All flight controls surfaces were accounted for at the accident site, and flight control continuity was confirmed from the cockpit to each control surface. The left wing was separated at the wing root and had thermal damage on the inboard portion. The right wing was still attached to the fuselage and sustained substantial thermal damage. The flap control handle indicated a flap position of 10°.

The cockpit and fuselage were destroyed by fire. Both propeller blades exhibited aft bending and leading-edge polishing. The landing gear was retracted.

The engine was rotated by hand at the propeller, and continuity of the drive train, valve train, and accessory section were established. The sparkplugs showed signs of normal wear. The magnetos were destroyed by fire. Thumb compression was confirmed on all cylinders. Examination of the engine and disassembly of its accessories revealed no evidence of any preimpact mechanical anomalies.

MEDICAL AND PATHOLOGICAL INFORMATION

The FAA's Bioaeronautical Sciences Research Laboratory, Oklahoma City, Oklahoma, performed toxicological testing of samples from the pilot, which were negative for ethanol and drugs of abuse.

ADDITIONAL INFORMATION

According to FAA Pamphlet FAA-P-8740-2, Density Altitude:

Whether due to high altitude, high temperature, or both, reduced air density (reported in terms of density altitude) adversely affects aerodynamic performance and decreases the engine's horsepower output. Takeoff distance, power available (in normally aspirated engines), and climb rate are all adversely affected. Landing distance is affected as well; although the indicated airspeed (IAS) remains the same, the true airspeed (TAS) increases. From the pilot's point of view, therefore, an increase in density altitude results in the following:

• Increased takeoff distance.

• Reduced rate of climb.

• Increased TAS (but same IAS) on approach and landing.

• Increased landing roll distance.

Because high density altitude has particular implications for takeoff/climb performance and landing distance, pilots must be sure to determine the reported density altitude and check the appropriate aircraft performance charts carefully during preflight preparation. A pilot's first reference for aircraft performance information should be the operational data section of the aircraft owner's manual or the Pilot's Operating Handbook developed by the aircraft manufacturer. In the example given in the previous text, the pilot may be operating from an airport at 500 ft MSL, but he or she must calculate performance as if the airport were located at 5,000 ft. A pilot who is complacent or careless in using the charts may find that density altitude effects create an unexpected –and unwelcome – element of suspense during takeoff and climb or during landing.

According to the Pilot's Handbook of Aeronautical Information, Chapter 3 (pg. 3-3, para. 1) per the section entitled Density Altitude (DA):

DA is the vertical distance above sea level in the standard atmosphere at which a given density is to be found. The density of air has significant effects on the aircraft's performance because as air becomes less dense, it reduces:

• Power because the engine takes in less air.

• Thrust because a propeller is less efficient in thin air.

• Lift because the thin air exerts less force on the air foils.

NTSB Probable Cause

The pilot's inadequate preflight weight and balance and performance planning, which resulted in the airplane being over gross weight. Also causal were the pilot's decision not to use the entire runway for takeoff, his premature liftoff, and his failure to attain adequate airspeed, which resulted in the airplane exceeding its critical angle of attack and an aerodynamic stall.
