## Sequence of events

In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf).

- Airframe/component/system failure/malfunction, takeoff - initial climb
  - flt control syst,elevator trim/tab control - binding(mechanical) (contributing factor)
  - flt control syst,elevator trim/tab control - undetermined (cause)
  - elevator trim - uncontrolled, pilot in command

## Analysis

WHILE CLIMBING THRU 500 FT AGL ON TAKEOFF, THE MANUAL PITCH TRIM STRUCK AT 1 OR 2 UNITS NOSE UP. USE OF THE THREE TRIM DISCONNECT SWITCHES DID NOT REMEDY THE PROBLEM. ABOUT 30 SECS LATER, THE PITCH TRIM RAN AWAY NOSE UP AND WOULD NOT STOP UNTIL THE PITCH TRIM CIRCUIT BREAKER WAS PULLED. MANUAL TRIM REMAINED INOP. THE PROBLEM CLEARED UP 2 OR 3 MINS LATER. SUBSEQUENT INVESTIGATION DISCLOSED EVIDENCE OF THE MANUAL PITCH TRIM CHAIN BINDING ON A STRINGER IN THE PEDESTAL. NO OTHER MALFUNCTIONS WERE IDENTIFIED. THE AIRCRAFT HAD A HISTORY OF MALFUNCTIONING MANUAL PITCH TRIM.
