Cessna 172P Skyhawk, N173LL, Lani Lea Sky Tours LLC: Accident occurred May 03, 2017 at Molokai Airport, Kaunakakai, Hawaii

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

Investigation Docket - National Transportation Safety Board:  https://dms.ntsb.gov/pubdms

NTSB Identification: GAA17CA268 
14 CFR Part 91: General Aviation
Accident occurred Wednesday, May 03, 2017 in Kaunakakai, HI
Probable Cause Approval Date: 10/31/2017
Aircraft: CESSNA 172, registration: N173LL
Injuries: 1 Uninjured.

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 student pilot reported that she was practicing touch-and-go landings on an asphalt runway. She initiated an approach and bounced the landing and then she initiated a go-around. She was airborne when she pushed the carb heat in and applied full throttle “but mistakenly put flaps up, all at once.” The airplane descended to the runway and landed hard. During the landing roll, she pulled the throttle back to idle, gained her bearings, and then initiated a takeoff. She noticed a binding and restriction in the elevator and yoke control movements while remaining in the airport’s pattern. She declared an emergency and landed the airplane on the runway. The airplane sustained substantial damage to the elevator control column.

The manufacturer’s Pilot’s Operating Handbook identified the Balked Landing procedure as:
Throttle – Full Open
Carburetor Heat – Cold
Wing Flaps –20° (Immediately)
Climb Speed – 55 KIAS
Wing Flaps – 10° (Until obstacles are cleared) Retract (After reaching a safe altitude and 60 KIAS)

The student reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation. 

The National Transportation Safety Board determines the probable cause(s) of this accident as follows:
The student pilot’s incorrect flap configuration during the go-around, which resulted in a hard, forced landing.

Additional Participating Entity:
Federal Aviation Administration / Flight Standards District Office; Honolulu, Hawaii
