  • Cooling system, cowling › Unlatched

Approximate · Estimated position: the centre of Burbank, CA, the place the record names. Not the accident site.

NTSB narrative

The upper engine cowling separated from the nose section during flight and lodged on the horizontal stabilizer. The cowling remained on the stabilizer until after landing and then fell off on the runway during the rollout. Postflight examination of portions of the upper cowl, which contained three fasteners, did not disclose any damage or excessive wear to the fasteners. However, the two front alignment pins that attach to the lower cowl were missing.

Probable cause

improperly secured upper cowl fasteners by unknown person(s).

  • 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: investigation status. Values present in the bulk record are kept.
  • The date is the local date, which is the same as the UTC date the NTSB stores.
