Mooney M20J 201, NM Liquors Inc, N1157N: Accident occurred March 28, 2017 at George T. Lewis Airport (KCDK), Cedar Key, Levy County, Florida

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: GAA17CA211
14 CFR Part 91: General Aviation
Accident occurred Friday, April 28, 2017 in Cedar Key, FL
Probable Cause Approval Date: 10/31/2017
Aircraft: MOONEY M20J, registration: N1157N
Injuries: 2 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 private pilot reported that, during the landing roll, he had traveled about halfway down the 2,355 ft-long runway when he realized that a go-around was going to be required. He could not recall the airplane’s airspeed when the airplane touched down on the runway that was located steps from the ocean. However, he did recall that he initiated the go-around by applying full throttle, retracting the flaps to 0, and rotating at 62 knots. The airplane “lifted off but did not gain altitude.” The pilot lowered the nose to accelerate, but the airplane stalled and impacted the water. The airplane sustained substantial damage to the right wing spar and aileron.  

According to the manufacturer’s Pilot’s Operating Handbook, the go-around procedure is:

CAUTION
To minimize control wheel forces during go-around, timely nose-down trimming is recommended to counteract nose up pitching moment as power is increased and/or flap retraction. 
Power…..Full Throttle/2700 RPM
Mixture…..Full Rich
Airspeed…..65 KIAS
Wing Flaps…..Takeoff position after climb established
Trim…..Nose Down (to reduce control forces)
Airspeed…..Accelerate to 76 KIAS
Landing Gear…..-Retract
Wing Flaps…..Retract
Cowl Flaps…..Open
Airspeed…..Accelerate to 86 KIAS

The pilot 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 pilot’s failure to follow the manufacturer’s go-around procedure, which resulted in an aerodynamic stall.

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 private pilot reported that during the landing roll, he had traveled about half of the distance down the 2,355 ft. runway and he realized that a go-around was going to be required. He could not recall the airplane's airspeed when the airplane touched down on the runway that was located steps from the ocean. However, he did recall that he initiated the go-around by applying full throttle, retracting the flaps to zero and rotating at 62 kts. The airplane "lifted off but did not gain altitude." The pilot lowered the nose to accelerate, but the airplane stalled and impacted the water. The airplane sustained substantial damage to the right wing spar and aileron.
