Narrative:

Arrived at airport during hail storm. Inspected aircraft during preflight for hail damage. Reported damage to maintenance, maintenance inspected aircraft. Aircraft reported to be airworthy. Flew from ZZZ to xyz. Xyz maintenance inspected aircraft and found to be unairworthy. Supplemental information from acn 511219: at about XA45 on may/xa/01, received a hail storm. I am a flight line mechanic that worked that saturday night/sunday morning. I had 2 aircraft parked at gates. I was in the process of troubleshooting an inoperative logo light when it began to hail. By about XA30 it was safe to return to the aircraft, at which point I closed up my logo light -- it needed to be deferred. The flight crew approached me to ask how the aircraft handled the hail. I let them know I would be right back out to check the plane for damage. Check maintenance manual to see if there was a required inspection to be followed and there was not. Contacted maintenance control to get logo light deferred and asked about how well the aircraft handle hail. He assured me (not knowing the exact size of the hail) that it doesn't normally cause too much if any damage. Know that I went back to inspect aircraft X that was due to depart at XB00. It was still raining quite hard and not quite daylight. The aircraft was inspected in a timely manner and no substantial damage was noted. Flight was informed and departed to xyz. There was no log page entry. The second aircraft I inspected was aircraft Y. Damage from hail included, but was not limited to, a hole in l-hand aileron. I contacted maintenance control to let him know about the damage to aircraft Y. He asked about aircraft X. I told him I didn't find any substantial damage. He let me know that they would look the aircraft over when it arrived in xyz. Upon doing so, the aircraft went to the hangar for repairs for damaged (dented) flight control. A deice truck was used to access the entire aircraft while I performed my inspection.

Title: DC9-10 CREW REQUESTED THEIR ACFT BE INSPECTED FOR HAIL DAMAGE PRIOR TO FLT.

Narrative: ARRIVED AT ARPT DURING HAIL STORM. INSPECTED ACFT DURING PREFLT FOR HAIL DAMAGE. RPTED DAMAGE TO MAINT, MAINT INSPECTED ACFT. ACFT RPTED TO BE AIRWORTHY. FLEW FROM ZZZ TO XYZ. XYZ MAINT INSPECTED ACFT AND FOUND TO BE UNAIRWORTHY. SUPPLEMENTAL INFO FROM ACN 511219: AT ABOUT XA45 ON MAY/XA/01, RECEIVED A HAIL STORM. I AM A FLT LINE MECH THAT WORKED THAT SATURDAY NIGHT/SUNDAY MORNING. I HAD 2 ACFT PARKED AT GATES. I WAS IN THE PROCESS OF TROUBLESHOOTING AN INOP LOGO LIGHT WHEN IT BEGAN TO HAIL. BY ABOUT XA30 IT WAS SAFE TO RETURN TO THE ACFT, AT WHICH POINT I CLOSED UP MY LOGO LIGHT -- IT NEEDED TO BE DEFERRED. THE FLC APCHED ME TO ASK HOW THE ACFT HANDLED THE HAIL. I LET THEM KNOW I WOULD BE RIGHT BACK OUT TO CHK THE PLANE FOR DAMAGE. CHK MAINT MANUAL TO SEE IF THERE WAS A REQUIRED INSPECTION TO BE FOLLOWED AND THERE WAS NOT. CONTACTED MAINT CTL TO GET LOGO LIGHT DEFERRED AND ASKED ABOUT HOW WELL THE ACFT HANDLE HAIL. HE ASSURED ME (NOT KNOWING THE EXACT SIZE OF THE HAIL) THAT IT DOESN'T NORMALLY CAUSE TOO MUCH IF ANY DAMAGE. KNOW THAT I WENT BACK TO INSPECT ACFT X THAT WAS DUE TO DEPART AT XB00. IT WAS STILL RAINING QUITE HARD AND NOT QUITE DAYLIGHT. THE ACFT WAS INSPECTED IN A TIMELY MANNER AND NO SUBSTANTIAL DAMAGE WAS NOTED. FLT WAS INFORMED AND DEPARTED TO XYZ. THERE WAS NO LOG PAGE ENTRY. THE SECOND ACFT I INSPECTED WAS ACFT Y. DAMAGE FROM HAIL INCLUDED, BUT WAS NOT LIMITED TO, A HOLE IN L-HAND AILERON. I CONTACTED MAINT CTL TO LET HIM KNOW ABOUT THE DAMAGE TO ACFT Y. HE ASKED ABOUT ACFT X. I TOLD HIM I DIDN'T FIND ANY SUBSTANTIAL DAMAGE. HE LET ME KNOW THAT THEY WOULD LOOK THE ACFT OVER WHEN IT ARRIVED IN XYZ. UPON DOING SO, THE ACFT WENT TO THE HANGAR FOR REPAIRS FOR DAMAGED (DENTED) FLT CTL. A DEICE TRUCK WAS USED TO ACCESS THE ENTIRE ACFT WHILE I PERFORMED MY INSPECTION.
