Narrative:

I was administering a private pilot asel add-on to a commercial rated helicopter applicant with instrument helicopter rating as well. During recovery from emergency descent; myself and applicant heard loud bang. Sounded like baggage door opening. Applicant stated he was having trouble flying aircraft and asked me to fly aircraft. IAS approximately 80 knots; altitude 1000 ftt. At 80 knots; I had trouble keeping aircraft going straight. Full left aileron; approximately full left rudder. I decided to slow aircraft and climb to approximately 2500 ft. At 2500 ft; I slowed aircraft to determine controllability at different airspeeds. Decision was made to fly 70 knots IAS on final. At this point we were 19 NM northwest of ZZZ with left flap at approximately 30 degrees; right flap 0 degrees. Flew back and landed; wind approximately 090 degrees at 10 gusting 13. Landed without incident. My concerns: 1) is this an 'ad' concern? 2) based on my experience; I believe this would be a major flight control issue for a private pilot. 3) I am 6'4' and it was very uncomfortable flying aircraft in this condition due to flight control pressures required to maintain control.

Original NASA ASRS Text

Title: C172 Examiner reports a left flap jammed at 30 degrees when the flaps are selected up after an emergency descent with the examinee at the controls. Examinee passes control of the aircraft to the Examiner due to controlability issues. Reporter finds aircraft marginally controllable but is able to climb and land at a suitable airport.
