Accident occurred Monday, June 20, 2016 in Honesdale, PA
Aircraft: CESSNA 172P, registration: N54285
Injuries: 3 Uninjured.
NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.
On June 20, 2016, at 1445 eastern daylight time, a Cessna 172P, N54285, was substantially damaged during a hard landing after takeoff from Cherry Ridge Airport (N30), Honesdale, Pennsylvania. The private pilot/owner, copilot, and one passenger were not injured. Visual meteorological conditions prevailed, and no flight plan was filed for the personal flight, which was conducted under the provisions of 14 Code of Federal Regulations Part 91.
In a written statement, the pilot stated he had flown from Morristown Airport (MMU), Morristown, New Jersey earlier in the day. He performed the preflight inspection, engine run-up, taxi, and takeoff for the earlier flight and the accident flight in accordance with the pilot operating handbook with no anomalies noted.
The pilot accelerated the airplane and performed the takeoff rotation at 65 knots after using "1/3" of the runway, which was 2,986 feet long. According to the pilot, "When I was about 30-40 feet in the air I felt the airplane was not climbing and I was not going to make it over the trees at the end of the runway." The pilot closed the throttle, landed on the runway, but over-ran the runway off the right side at the departure end. The airplane continued down a steep embankment and came to rest nose down in low brush.
In a telephone interview, the copilot stated that the pilot performed a walk-around and checked both the fuel and oil, and then he assisted him with the before starting engine and takeoff checklists. "Everything sounded normal, we taxied down, lined up at the approach end of runway 18, slowly advanced the throttle, reached full power and accelerated down the runway". The copilot called "65 knots" and rotate. At the time the airplane rotated, he activated the noise-cancelling feature of his headphones.
The copilot said he couldn't hear if there was a power interruption, but he did hear the pilot announce that he was landing back on the runway. After landing, the airplane nearly stopped on the runway, but carried off the right side at the departure end.
A review of surveillance video showed the wings of the airplane rocking immediately after liftoff at the mid-point of the runway. The pitch attitude increased, but the airplane never climbed more than 15 feet above ground level before the airplane leveled suddenly, and then fell hard to the runway on all three landing gear with approximately 675 feet remaining. The airplane bounced several times, and settled on all three landing gear with 500 feet of the runway remaining. The airplane was then seen departing the right side of the runway at the departure end.
According to Federal Aviation Administration (FAA) records, the pilot held a private pilot certificate with a rating for airplane single-engine land. He was issued an FAA third-class medical certificate on April 28, 2015. The pilot reported 878 total hours of flight experience, all of which was in the accident airplane make and model.
The four-seat, single-engine, high-wing airplane was manufactured in 1981, and was equipped with a Lycoming O-320, 160-horsepower engine. Its most recent annual inspection was completed on May 26, 2016 at 9,703.9 aircraft hours.
According to the pilot, the maximum allowable gross weight for the airplane was 2,400 pounds. According to his calculations based on passenger, fuel, and baggage weights, the airplane weighed 2,255 pounds at takeoff from N30.
Examination of the airplane by an FAA inspector revealed substantial damage to the airplane's wings due to the hard landing, but no preimpact mechanical anomalies. He then attempted an engine start with the airplane's own battery. The engine started immediately, accelerated smoothly, and ran continuously without interruption.
At 1455 the temperature reported at Sullivan County Airport (MSV), Monticello, New York, 23 miles northeast of N30, was 29 degrees C, dewpoint was 14 degrees C, and the altimeter setting was 30.09 inches of mercury.
The copilot stated that it was "warmer" at Morristown Municipal Airport (MMU), Morristown, New Jersey, at 186 feet elevation when they departed for N30 about 1200. The calculated density altitude at MMU at that time was 1,524 feet.
The calculated density altitude for N30 at the time of the accident, at 1,357 feet elevation, was 3,297 feet. At 2,000 feet density altitude, the calculated ground roll to stop the airplane was 610 feet.
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 MSL, but he or she must calculate performance as if the airport were located at 5,000 feet. 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.
CHERRY RIDGE TOWNSHIP -- No one was hurt when a small plane crashed Monday afternoon at the Cherry Ridge Airport outside Honesdale.
Emergency crews say the Cessna 172P Skyhawk went down around 3 p.m.
Photos of the crash are from the Wayne County Fire/EMS Alerts Facebook page.
The manager of the airport said the plane crashed while trying to take off.
There is no word who was in the plane, but again, officials say no one was hurt.
