During the landing roll, the airplane exited the right side of the runway. He increased power to abort the landing, and the left horizontal stabilizer struck a runway sign. He continued the climb the airplane and flew one pattern and landed. The airplane sustained substantial damage to the left horizontal stabilizer and the rudder. The instructor reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation. ## Factual narrative The flight instructor reported that while administering a flight review in the tailwheel-equipped airplane, he took the controls to demonstrate a full stall landing, during the landing roll, the airplane exited the right side of the runway. He increased power to abort the landing, and the left horizontal stabilizer struck a runway sign. He continued the climb and flew one pattern and landed. The airplane sustained substantial damage to the left horizontal stabilizer and the rudder. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation. ## Aircraft - Registration: N9225G (not matched to a registry record) - Reported make and model: Maule MX7 (180A) - Category: Airplane - Serial number: 20001C - Airframe hours: 1335 - Engines: Lycoming O-360-C4F 180 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Operator: Ave Av Llc - Registered owner: Ave Av Llc - Airworthiness certificate: Standard, Normal - Last inspection: Annual, September 16, 2018 - Departed: IMM, IMMOKALEE, FL - Destination: IMM, IMMOKALEE, FL - Airport: IMM, Immokalee Rgnl, runway 09, 5,000 × 100 ft, asphalt - Equipment: Satellite tracking device, Electronic flight bag or handheld device, Auto-pilot ## Flight crew As NTSB recorded them.
