NTSB narrative
PLT STATED THAT THE ACFT PITCHED 20 DEG NOSE DOWN WITHOUT WARNING WHILE IN CRUISE FLT AT 1,200' AND 120 KTS. FOLLOWING RECOVERY, THE ACFT REQUIRED ADDITIONAL RT PEDAL TO STAY IN TRIM AND IT FLEW ABOUT 10 DEG NOSED DOWN IN LVL FLT. FLT DIVERTED TO THE OPR'S BASE AND LANDED SUCCESSFULLY. EXAMINATION REVEALED THAT THE RT HORZ STAB HAD SEPARATED JUST OUTBOARD OF THE TAILBOOM. METALLURGICAL EXAMINATION OF THE SEPARATION REVEALED MULTIPLE FATIGUE ORIGINS IN THE AREAS OF BOTH THE FORWARD AND AFT TOP SPAR CAP RIVET HOLES AND THAT THE CRACK IN THE AFT SPAR HAD BEEN PRESENT FOR SOME TIME. PREVIOUS FAILURES IN THIS AREA HAD BEEN ATTRIBUTED TO WORKING RIVETS CAUSING STRESS CONCENTRATIONS IN THE RIVET HOLES. PREVENTION OF THIS TYPE FAILURE IS EFFECTED BY REPLACING THE AFFECTED RIVETS IN A TIMELY MANNER. MAINTENANCE RECORDS REVEALED THAT THE LEFT HORIZONTAL STABILIZER HAD BEEN REPAIRED ON 3 PRIOR OCCASIONS, BUT THERE WERE NO RECORDS OF REPAIRS ON THE RT STABILIZER.

Source notes (4)
- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: local date, investigation status. Values present in the bulk record are kept.
- The date is the local date; the NTSB stores the UTC date 1988-08-07.
