NTSB narrative

THE PILOT HAD FLOWN TO LANCASTER, PA. TO PICK UP THE 'BEST MAN' FOR HIS WEDDING. THE PILOT FILED AN IFR FLIGHT PLAN AND DEPARTED IN IFR CONDITIONS. APPROXIMATELY 15 MINUTES LATER, THE PILOT REPORTED THAT HE HAD LOST THE HORIZON INDICATOR, BUT WAS GOING TO CONTINUE TO HIS DESTINATION. THE CONTROLLER ISSUED A CLEARANCE TO CLIMB TO 6,000 FT. AND A SHORT TIME LATER, THE PILOT STATED '...ITS PRETTY HAZY HERE BUT I KNOW WE'RE ON TOP BUT I DON'T KNOW IF I WANT TO GO ANY HIGHER.' SHORTLY THEREAFTER, THE PILOT REPORTED THE 'ELECTRIC COMPASS AND TURN AND BANK INDICATOR' HAD FAILED. ACCORDING TO RADAR DATA, THE MAXIMUM ALTITUDE ATTAINED BY N82718B WAS 5,700 FT. POST ACCIDENT EXAMINATION OF THE AIRPLANE'S VACUUM SYSTEM REVEALED NO EVIDENCE OF A PRE IMPACT FAILURE. TOXICOLOGY TEST REVEALED A LEVEL OF 1.1 MG/KG OF ANTIHISTAMINE IN THE PILOT'S BODY.

Probable cause

THE PILOT'S LOSS OF AIRPLANE CONTROL DUE TO SPATIAL DISORIENTATION/VERTIGO. FACTORS RELATED TO THE ACCIDENT WERE THE PILOT'S USE OF AN ANTIHISTAMINE AND SELF INDUCED PRESSURE TO COMPLETE THE FLIGHT.

  • 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.
