What was found
BEFORE LANDING, PILOT SELECTED 10 DEGREES FLAPS & ACFT DRIFTED LT. ABORTED LANDING, RAISED FLAPS & DID A GO AROUND THINKING, THAT ONE OF THE MLG HAD NOT COME DOWN. AT THE 2ND ATTEMPT, HAD SAME PROBLEM & REALIZED THE PROBLEM WAS NOT THE MLG, BUT THE FLAP SYS. RT FLAP HAD NOT GONE DOWN, RAISED FLAPS AGAIN & LANDED WITHOUT FLAPS. AFTER LDG, A FUNCTIONAL CHECK OF FLAPS, NO ABNORMALITIES. AFTER INSP, RT FLAP INBOARD BELLCRANK FOUND CRACKED ABOUT 80% OF CIRCUMFERENCE. OTHER BELLCRANKS OF BOTH FLAPS WERE VISUALLY INSP & NO PROBLEM FOUND. PILOTS STATES, THAT HE & OTHER PILOTS HAVE NEVER LOWERED THE FLAPS AT SPEEDS HIGHER THAN THOSE SPECIFIED IN THE ACFT POH.
