What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
A student pilot and certificated flight instructor (CFI) were conducting touch-and-go landings at Falcon field (ffz) in Mesa, Arizona. After completing one landing, the aircraft departed runway 4R and, during climb-out at approximately 200 feet AGL, experienced an uncommanded reduction in engine power to below 1700 RPM.
The PIC notified ATC and was cleared to land on runway 22L. During landing, maximum braking was applied, resulting in excessive wear and deflation of both main landing gear tires. After landing, the PIC observed that cylinder number 2 was significantly cooler than the other cylinders.
Post-event maintenance inspection, including borescope and compression checks, identified low compression in cylinder number 2 due to a stuck exhaust valve. Maintenance personnel reamed the number 2 exhaust valve in accordance with applicable guidance, restoring normal engine operation.
As the FAA filed it
A STUDENT PILOT AND CERTIFICATED FLIGHT INSTRUCTOR (CFI) WERE CONDUCTING TOUCH-AND-GO LANDINGS AT FALCON FIELD (FFZ) IN MESA, ARIZONA. AFTER COMPLETING ONE LANDING, THE AIRCRAFT DEPARTED RUNWAY 4R AND, DURING CLIMB-OUT AT APPROXIMATELY 200 FEET AGL, EXPERIENCED AN UNCOMMANDED REDUCTION IN ENGINE POWER TO BELOW 1700 RPM.
THE PIC NOTIFIED ATC AND WAS CLEARED TO LAND ON RUNWAY 22L. DURING LANDING, MAXIMUM BRAKING WAS APPLIED, RESULTING IN EXCESSIVE WEAR AND DEFLATION OF BOTH MAIN LANDING GEAR TIRES. AFTER LANDING, THE PIC OBSERVED THAT CYLINDER NUMBER 2 WAS SIGNIFICANTLY COOLER THAN THE OTHER CYLINDERS.
POST-EVENT MAINTENANCE INSPECTION, INCLUDING BORESCOPE AND COMPRESSION CHECKS, IDENTIFIED LOW COMPRESSION IN CYLINDER NUMBER 2 DUE TO A STUCK EXHAUST VALVE. MAINTENANCE PERSONNEL REAMED THE NUMBER 2 EXHAUST VALVE IN ACCORDANCE WITH APPLICABLE GUIDANCE, RESTORING NORMAL ENGINE OPERATION.
