## Sequence of events

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

- Airframe/component/system failure/malfunction, approach - vfr pattern - final approach
  - flight control,flap attachment - separation (cause)
  - maintenance,major repair - improper, other maintenance personnel (cause)

## Analysis

THE ACFT EXPERIENCED THE SEPARATION OF A FLAP VANE WHILE ON FINAL APPROACH TO LAND. 50 INCHES OF THE RIGHT FLAP VANE SEPARATED AND CAUSED SLIGHT DAMAGE TO A PARKED AUTO ON THE STREET BELOW. THE ACFT CONTINUED ON TO AN UNEVENTLY LANDING. THE INCIDENT WAS NOT NOTICED UNTIL A LOCAL RESIDENT CALLED TO REPORT THE FALLEN ARTICLE. ALL DC-10 OPERATORS WERE NOTIFIED BY TELEX OF THE FAILURE DUE TO DELAMINATION OF THE VANE FROM MOISTURE INGESTION. A SKIN REPAIR HAD BEEN MADE INTHIS CASE AND A COLD BOND METHOD WITH INADEQUATE SURFACE PREPARATION AND INSUFFICIENT PRESSURE DURING BONDING WERE MAJORFACTORS IN THE FAILURE OF THE BOND. THE IDENTITY OF THE FACILITY THAT MADE THE BOND REPAIR TO THE VANE WAS NOT DETERMINED.
