FAA Flight Standards District Office: FAA Fresno FSDO-17

NTSB Identification: GAA16CA311
14 CFR Part 91: General Aviation
Accident occurred Friday, May 27, 2016 in Groveland, CA
Probable Cause Approval Date: 08/31/2016
Aircraft: CHAMPION AERONCA 7AC, registration: N2675E
Injuries: 1 Minor.

NTSB investigators used data provided by various entities, including, but not limited to, the Federal Aviation Administration and/or the operator and did not travel in support of this investigation to prepare this aircraft accident report.

The pilot of a tailwheel-equipped airplane reported that during the landing roll, a "strong gust" of wind lifted the left wing and the airplane veered off the runway to the right. During the runway excursion, the airplane impacted a concrete barrier wall in the ramp area. The firewall sustained substantial damage.

The pilot did not report any mechanical malfunctions or failures with the airplane that would have precluded normal operation. 

The nearest automated weather observing station 15 nautical miles away from accident airport, about the time of the accident, reported the wind at 210 degrees true at 4 knots. The airplane landed on a 270 degrees magnetic heading.

The National Transportation Safety Board determines the probable cause(s) of this accident as follows:
The pilot's failure to maintain directional control during the landing roll in gusty crosswind conditions, which resulted in a runway excursion and a collision with a concrete barrier wall.







Pine Mountain Lake, CA — Tuolumne County Sheriff’s Deputies are on the scene of a crash landing that left a woman pilot injured.

The crash happened just before 1:30 p.m. Friday at the Pine Mountain Lake Airport in Groveland. 

Sgt. Andrea Benson states the Aeronca 7AC Champion was attempting to land when the aircraft swerved off the runway.

The plane then smashed into a wall at the fuel depot. Luckily, there was no damage or rupture of the fuel tanks, according to Sgt. Benson.

The pilot, 61-year-old Charleen Beam from Groveland, suffered an ankle injury and was taken by ambulance to an area hospital for evaluation.  

Sgt. Benson notes that Beam told deputies that “heavy crosswinds caused the aircraft to veer off the runway.”

The Federal Aviation Administration and the National Transportation Safety Board have been notified of the downed plane and will be investigating the accident.

This is the second plane crash at the airport in a month, as previously reported on May 10 a Beech B24R Sierra crashed just after takeoff. The pilot and passenger were not injured in that crash but one did have a cut to his hand.

Aviation Accident Final Report - National Transportation Safety Board: https://app.ntsb.gov/pdf

NTSB Identification: WPR16LA105 
14 CFR Part 91: General Aviation
Accident occurred Tuesday, May 10, 2016 in Groveland, CA
Probable Cause Approval Date: 09/06/2017
Aircraft: BEECH B24R, registration: N2052L
Injuries: 2 Minor.

NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.

The passenger, who was a student pilot, recently purchased the airplane in an estate sale. He and the airline transport pilot, both of whom lived in Mississippi, had traveled to California to retrieve the airplane and fly it back to Mississippi. Before the purchase, the airplane had not been maintained, operated, or flown in almost 11 years. Following the purchase, the owner contracted with a mechanic in California to ensure the airplane was in airworthy condition, which the mechanic reportedly did. The day before the accident, the pilot and owner took the airplane for its first flight after its dormant period and flew one uneventful circuit in the airport traffic pattern, as planned. The following day, the pilot and owner planned to fly the airplane for some systems evaluations. During that takeoff attempt from runway 9, the airplane became airborne but failed to climb and struck trees and terrain beyond the runway end. Although the pilot believed that he was taking off into the wind, witness statements and other evidence indicated that the takeoff was attempted with an approximate 5-knot tailwind. The first 1,000 ft of the runway was level, but the remaining 2,000 ft was sloped uphill. Although the Pilot’s Operating Handbook specified using 15° flaps for takeoff, and the pilot reported that he used that setting and did not alter the flap position during the flight, the flaps were found to have been fully retracted at impact.

Surveillance camera imagery captured about 2 seconds of the flight, when the airplane was about midfield and 4 ft above ground level (agl). Review of that imagery and audio data indicated that the ground speed was about 68 knots and that the engine speed was about 2,640 rpm; both values were consistent with normal takeoff values. However, the exact winds (and thus airspeed) were unknown, and because the propeller was a constant-speed model, nominal takeoff rpm could be achieved even if the engine was not developing full-rated power.

Detailed examination of the airplane, including the engine, revealed that, although its condition was not in accordance with Federal Aviation Administration and manufacturer guidance, none of the observed deficiencies could have caused or contributed to the loss of climb performance, except for one magneto that was found to be mistimed to the engine by 7°. Evidence suggested that this was likely a result of the accident but that could not be determined with certainty. Performance calculations conducted by the airplane manufacturer, which accounted for most of the known takeoff conditions, including fully retracted flaps, indicated that the distance to 50 ft agl was slightly more than the available runway. The estimated airplane takeoff weight was about 300 lbs (11%) below the maximum takeoff weight that was used in the calculations, which would yield better performance than the calculated results. However, those calculations did not account for off-nominal values of the many other variables that could adversely affect takeoff performance, including pilot technique, airframe and engine deterioration, and inaccurate or improperly set instrumentation and controls. Thus, although a successful downwind takeoff with no flaps was unlikely, it might have been possible, but there were too many other unknowns to determine its likelihood with greater certainty.

The reason(s) for the retracted flaps could not be determined. It is possible that the pilot forgot to extend them or that they were inadvertently and unknowingly retracted. Given the location of the flap control switch and its design (momentary, paddle-type), it is possible that the pilot extended the flaps to the proper takeoff setting of 15° but that they were subsequently retracted when the nonpilot passenger inadvertently contacted and actuated the flap control. The size and location of the flap position indicator gauge, combined with the location of the flaps (behind the pilot on the low-wing airplane), minimized the possibility that the pilot would notice that they had been retracted.

The National Transportation Safety Board determines the probable cause(s) of this accident as follows:
The pilot's decision to conduct an upslope, downwind takeoff combined with an improper flap setting, which resulted in the airplane's inability to clear trees beyond the runway end. The reason for the improper flap setting could not be determined.


Beech B24R Sierra, N2052L: Accident occurred May 10, 2016 at & Pine Mountain Lake Airport (E45), Groveland, Tuolumne County, California

FAA Flight Standards District Office:  FAA Fresno FSDO-17

NTSB Identification: WPR16LA105
14 CFR Part 91: General Aviation
Accident occurred Tuesday, May 10, 2016 in Groveland, CA
Aircraft: BEECH B24R, registration: N2052L
Injuries: 2 Minor.

This is preliminary information, subject to change, and may contain errors. Any errors in this report will be corrected when the final report has been completed. 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 May 10, 2016, about 1215 Pacific daylight time, a Beech B24R Sierra, N2052L, was substantially damaged when it impacted terrain during an attempted departure from Pine Mountain Lake airport (E45), Groveland, California. The pilot and the passenger/owner received minor injuries. The personal flight was conducted under the provisions of Title 14 Code of Federal Regulations Part 91. Visual meteorological conditions prevailed.

The passenger, who was a student pilot, recently purchased the airplane in an estate sale. Both the pilot and owner lived in Mississippi, and had traveled to E45 to retrieve the airplane, and fly it back to Mississippi. The airplane was domiciled at E45, and reportedly had not been maintained, operated, or flown in at least 5 years, and possibly 10 or more. The airplane's most recent Federal Aviation Administration (FAA) registration expired in 2011. Subsequent to the purchase, the owner contracted with a mechanic at E45 to conduct maintenance on it, in preparation for the flight to Mississippi.

The day prior to the accident, both fuel tanks were filled, and the pilot and owner took the airplane for its first flight after its dormancy. The airplane departed on runway 27, and flew one circuit in the pattern, as planned. That flight was uneventful. The next day, they planned to again fly the airplane, this time departing the area for some systems evaluations before returning to E45. This takeoff attempt, which terminated in the accident, was conducted on runway 9. The pilot reported that the first part of the takeoff roll and liftoff "appeared normal but during or at gear retraction the aircraft started losing power." He stated with about 1,000 feet of runway remaining, the engine "was not producing enough power to climb or accelerate," and that it was apparent the airplane not going to clear the trees beyond the runway end. The pilot focused on attempting to climb, while simultaneously avoiding a stall. 

The airplane struck trees and a utility pole, and then thick underbrush and the ground. The airplane came to rest about 1,800 feet beyond the end of the runway, at a point slightly north of the extended runway centerline. The fracture-separated outboard right wing was located adjacent to the utility pole, and the engine had separated from the fuselage. The fuselage was slightly crumpled and otherwise deformed, but the cabin retained its normal occupiable volume. There was no fire.

The pilot reported that for both flights, he was seated in the left seat, and was the sole manipulator of the controls. He held an airline transport pilot certificate, and reported about 22,800 total hours of flight experience, including about 4,310 hours in single engine airplanes. Prior to his flight in the airplane the day before the accident, the pilot had no experience in the accident airplane make and model. His most recent flight review was completed in May 2015, and his most recent FAA third-class medical certificate was issued in January 2015.

FAA information indicated that the airplane was manufactured in 1976, and was equipped with a Lycoming IO-360 series engine.

E45 was equipped with a single paved runway, designated 9/27, which measured 3,624 by 50 feet. The airport elevation was listed in the FAA database as 2,932 feet. Runway 9 threshold elevation was 2,895 ft, and runway 27 threshold elevation was 2,932 ft.
