Narrative:

On feb/thu/97 I was the PIC of first aircraft, a C172, on a ferry flight from dab to X47. The time was approximately AB00 am, the WX was VFR. I contacted clearance delivery to obtain a VFR clearance for a flight of 2 banner tow aircraft and was told to contact ground for taxi. Calling ground with ATIS information, my aircraft was cleared to taxi via taxiway south to taxiway west, right on taxiway west to make a right turn to hold short at runway 7L. The aircraft proceeded onto taxiway south and company aircraft #2 was following aircraft #1. As we approached intersecting runway 16/34, I slowed to clear the area prior to crossing. As I slowed, aircraft #2 taxied into the tail of my aircraft. The left wing of aircraft #2, a C172, struck the rudder of aircraft #1 and then veered to the right. #2 aircraft sustained a dent in the leading edge of the left wing near the strut attach point. #1 aircraft sustained damage to the vertical stabilizer and rudder. Airport operations had us taxi both aircraft back to the hangar and secure them. The problem began at the company hangar. We had 1 hour to move the airplane to X47, top them off and pick up and pull the first of many banners for that day. The pilots were rushed by the boss and told to depart as a flight of 2, and neither pilot had much experience with that operation. Both planes were taxiing fairly close together and the pilots have not operated together that much, therefore I feel each pilot was not fully aware of what actions the other pilot would take. To correct the problem for this incident, more time should have been allotted for the ferry process. Human performance considerations include pilots had good rest, both are in good health (class I medical). In my opinion, both pilots made a bad judgement call with regard to accepting orders from the boss to do something neither pilot was very familiar with (flight of 2) and allowing ourselves to be rushed. Time limits were also contributing. Poor judgement decision.

Title: FORMATION FLT OF 2 C172 AS TAXIING TFC. #2 COLLIDES WITH #1 DURING TAXI PROC.

Narrative: ON FEB/THU/97 I WAS THE PIC OF FIRST ACFT, A C172, ON A FERRY FLT FROM DAB TO X47. THE TIME WAS APPROX AB00 AM, THE WX WAS VFR. I CONTACTED CLRNC DELIVERY TO OBTAIN A VFR CLRNC FOR A FLT OF 2 BANNER TOW ACFT AND WAS TOLD TO CONTACT GND FOR TAXI. CALLING GND WITH ATIS INFO, MY ACFT WAS CLRED TO TAXI VIA TXWY S TO TXWY W, R ON TXWY W TO MAKE A R TURN TO HOLD SHORT AT RWY 7L. THE ACFT PROCEEDED ONTO TXWY S AND COMPANY ACFT #2 WAS FOLLOWING ACFT #1. AS WE APCHED INTERSECTING RWY 16/34, I SLOWED TO CLR THE AREA PRIOR TO XING. AS I SLOWED, ACFT #2 TAXIED INTO THE TAIL OF MY ACFT. THE L WING OF ACFT #2, A C172, STRUCK THE RUDDER OF ACFT #1 AND THEN VEERED TO THE R. #2 ACFT SUSTAINED A DENT IN THE LEADING EDGE OF THE L WING NEAR THE STRUT ATTACH POINT. #1 ACFT SUSTAINED DAMAGE TO THE VERT STABILIZER AND RUDDER. ARPT OPS HAD US TAXI BOTH ACFT BACK TO THE HANGAR AND SECURE THEM. THE PROB BEGAN AT THE COMPANY HANGAR. WE HAD 1 HR TO MOVE THE AIRPLANE TO X47, TOP THEM OFF AND PICK UP AND PULL THE FIRST OF MANY BANNERS FOR THAT DAY. THE PLTS WERE RUSHED BY THE BOSS AND TOLD TO DEPART AS A FLT OF 2, AND NEITHER PLT HAD MUCH EXPERIENCE WITH THAT OP. BOTH PLANES WERE TAXIING FAIRLY CLOSE TOGETHER AND THE PLTS HAVE NOT OPERATED TOGETHER THAT MUCH, THEREFORE I FEEL EACH PLT WAS NOT FULLY AWARE OF WHAT ACTIONS THE OTHER PLT WOULD TAKE. TO CORRECT THE PROB FOR THIS INCIDENT, MORE TIME SHOULD HAVE BEEN ALLOTTED FOR THE FERRY PROCESS. HUMAN PERFORMANCE CONSIDERATIONS INCLUDE PLTS HAD GOOD REST, BOTH ARE IN GOOD HEALTH (CLASS I MEDICAL). IN MY OPINION, BOTH PLTS MADE A BAD JUDGEMENT CALL WITH REGARD TO ACCEPTING ORDERS FROM THE BOSS TO DO SOMETHING NEITHER PLT WAS VERY FAMILIAR WITH (FLT OF 2) AND ALLOWING OURSELVES TO BE RUSHED. TIME LIMITS WERE ALSO CONTRIBUTING. POOR JUDGEMENT DECISION.
