Narrative:

This report involves an incident when an aircraft was struck by lightning and inspected and returned to service then 3 flts later damage caused by a lightning strike was found and an issue was raised by management as to whether or not the damage was from the initial strike or from an additional strike later that day. I performed the inspection per the manufacturer's maintenance manual and found only negligible burn marks, that cleaned up easily. Additional damage was found later that night on a scheduled overnight check. After reviewing the facts, management concluded that the aircraft had been struck a second time. The aircraft was ferried to the maintenance base for repairs. Safety of flight never was an issue. The possibility does exist that the damage was missed on the initial inspection. The flight crew did walk around the aircraft and point out spots which they thought were burn marks that turned out to be paint overspray. This was somewhat distracting until maintenance personnel asked them to go take a coffee break.

Title: A FOKKER 28 WAS DISPATCHED AFTER A RPTED LIGHTNING STRIKE INSPECTION BUT WAS LATER FOUND TO HAVE MORE UNRPTED DAMAGE.

Narrative: THIS RPT INVOLVES AN INCIDENT WHEN AN ACFT WAS STRUCK BY LIGHTNING AND INSPECTED AND RETURNED TO SVC THEN 3 FLTS LATER DAMAGE CAUSED BY A LIGHTNING STRIKE WAS FOUND AND AN ISSUE WAS RAISED BY MGMNT AS TO WHETHER OR NOT THE DAMAGE WAS FROM THE INITIAL STRIKE OR FROM AN ADDITIONAL STRIKE LATER THAT DAY. I PERFORMED THE INSPECTION PER THE MANUFACTURER'S MAINT MANUAL AND FOUND ONLY NEGLIGIBLE BURN MARKS, THAT CLEANED UP EASILY. ADDITIONAL DAMAGE WAS FOUND LATER THAT NIGHT ON A SCHEDULED OVERNIGHT CHK. AFTER REVIEWING THE FACTS, MGMNT CONCLUDED THAT THE ACFT HAD BEEN STRUCK A SECOND TIME. THE ACFT WAS FERRIED TO THE MAINT BASE FOR REPAIRS. SAFETY OF FLT NEVER WAS AN ISSUE. THE POSSIBILITY DOES EXIST THAT THE DAMAGE WAS MISSED ON THE INITIAL INSPECTION. THE FLC DID WALK AROUND THE ACFT AND POINT OUT SPOTS WHICH THEY THOUGHT WERE BURN MARKS THAT TURNED OUT TO BE PAINT OVERSPRAY. THIS WAS SOMEWHAT DISTRACTING UNTIL MAINT PERSONNEL ASKED THEM TO GO TAKE A COFFEE BREAK.
