INADEQUATE WEATHER EVALUATION AND INADEQUATE SUPERVISION OF THE GROUND GUIDE (MECHANIC) BY COMPANY/OPERATOR/MANAGEMENT PERSONNEL, FAILURE OF THE GROUND GUIDE TO FOLLOW SAFETY PROCEDURES, AND THE WEATHER CONDITION (LIGHTNING).

Factual narrative

RAINFALL BECAME MODERATE TO HEAVY AS THE ACFT WAS BEING PUSHED BACK IN PREPARATION FOR FLT. DURING THAT TIME, LIGHTNING STRUCK THE TAIL OF THE ACFT WHILE A MECHANIC (GROUND GUIDE) WAS WEARING A HEADSET CONNECTED TO THE ACFT. THE LIGHTNING TRAVELED THRU THE ACFT & FATALLY INJURED THE MECHANIC. WITNESSES & SUPERVISORS STATED THAT THEY HAD OBSERVED LIGHTNING IN THE AREA BEFORE THE ACDNT, BUT THEY HAD NOT OBSERVED ANY FOR ABOUT 15 MIN; PUSH BACK WAS INITIATED AFTER PHONE CONVERSATION WITH TOWER PSNL. THE AIRLINE'S SAFETY MANUAL PROHIBITED GROUND GUIDE OPN DURING PERIODS OF OBSERVED LIGHTNING. Source: NTSB Aviation Accident Database (Pre-2008 Archive) Retrieved: 2026-02-12
