Narrative:

I was contracted to fly a lear 35 to tcl. While going through preflight and then taxi checks, I noticed that the directional gyros were not aligned properly between the captain's and copilot's side. We were holding short of the runway, waiting to take the active for takeoff. After making several attempts to remedy the problem and no success, I called maintenance. We decided to taxi back to the hangar to fix the problem. At that time, I asked maintenance if there was enough room to taxi in and make a 180 degree turn, at which time he informed me there was plenty of room. I proceeded taxiing back to the hangar, which was down at the end of the hangar row. Hangars were to the left and to the right of my airplane. When I reached the hangar, maintenance personnel were there to marshall me in. I decided to make a left turn in 180 degrees. As I was approaching the marshaler and my right wing was getting close to the hangars at my right, the marshaler ran back into the hangar to retrieve something. At that time, I asked my first officer if I was clear on my right. He informed me yes, but I was close. I then made a left turn 180 degrees. Upon stopping and shutting down, the maintenance personnel noticed that my right wingtip on the tip tank was bent. I had made contact with a hangar door and my right wingtip. The company that I was contracted with could have had procedures in place to handle taxi in and turnaround procedures while marshalling aircraft. A safety training program would have helped. The first officer that was contracted had only been in the airplane a couple of times and was not typed. After the incident he said 'I knew we hit the hangar and I should have exercised more authority/authorized and said stop.' having someone more familiar with the aircraft would have helped. My first instinct was not to taxi down the alley and make the 180 degree turn. I should have followed that instinct and stopped and had a tug turn the airplane around.

Title: WINGTIP STRIKE ON A HANGAR DOOR BY THE PIC OF A LEAR 35 RETURNING TO THE HANGAR WITH A DIRECTIONAL GYRO PROB AT SRQ, FL.

Narrative: I WAS CONTRACTED TO FLY A LEAR 35 TO TCL. WHILE GOING THROUGH PREFLT AND THEN TAXI CHKS, I NOTICED THAT THE DIRECTIONAL GYROS WERE NOT ALIGNED PROPERLY BTWN THE CAPT'S AND COPLT'S SIDE. WE WERE HOLDING SHORT OF THE RWY, WAITING TO TAKE THE ACTIVE FOR TKOF. AFTER MAKING SEVERAL ATTEMPTS TO REMEDY THE PROB AND NO SUCCESS, I CALLED MAINT. WE DECIDED TO TAXI BACK TO THE HANGAR TO FIX THE PROB. AT THAT TIME, I ASKED MAINT IF THERE WAS ENOUGH ROOM TO TAXI IN AND MAKE A 180 DEG TURN, AT WHICH TIME HE INFORMED ME THERE WAS PLENTY OF ROOM. I PROCEEDED TAXIING BACK TO THE HANGAR, WHICH WAS DOWN AT THE END OF THE HANGAR ROW. HANGARS WERE TO THE L AND TO THE R OF MY AIRPLANE. WHEN I REACHED THE HANGAR, MAINT PERSONNEL WERE THERE TO MARSHALL ME IN. I DECIDED TO MAKE A L TURN IN 180 DEGS. AS I WAS APCHING THE MARSHALER AND MY R WING WAS GETTING CLOSE TO THE HANGARS AT MY R, THE MARSHALER RAN BACK INTO THE HANGAR TO RETRIEVE SOMETHING. AT THAT TIME, I ASKED MY FO IF I WAS CLR ON MY R. HE INFORMED ME YES, BUT I WAS CLOSE. I THEN MADE A L TURN 180 DEGS. UPON STOPPING AND SHUTTING DOWN, THE MAINT PERSONNEL NOTICED THAT MY R WINGTIP ON THE TIP TANK WAS BENT. I HAD MADE CONTACT WITH A HANGAR DOOR AND MY R WINGTIP. THE COMPANY THAT I WAS CONTRACTED WITH COULD HAVE HAD PROCS IN PLACE TO HANDLE TAXI IN AND TURNAROUND PROCS WHILE MARSHALLING ACFT. A SAFETY TRAINING PROGRAM WOULD HAVE HELPED. THE FO THAT WAS CONTRACTED HAD ONLY BEEN IN THE AIRPLANE A COUPLE OF TIMES AND WAS NOT TYPED. AFTER THE INCIDENT HE SAID 'I KNEW WE HIT THE HANGAR AND I SHOULD HAVE EXERCISED MORE AUTH AND SAID STOP.' HAVING SOMEONE MORE FAMILIAR WITH THE ACFT WOULD HAVE HELPED. MY FIRST INSTINCT WAS NOT TO TAXI DOWN THE ALLEY AND MAKE THE 180 DEG TURN. I SHOULD HAVE FOLLOWED THAT INSTINCT AND STOPPED AND HAD A TUG TURN THE AIRPLANE AROUND.
