Narrative:

On feb/sat/07; I was asked to take aircraft X out for a maintenance run. The engine build up shop had just changed the fuel flow governor on the #2 engine. I walked into XXX to check on the progress of the work. The mechanics that were assigned to aircraft X were changing the #2 brake. They were having difficulties installing the tire; so I helped them install the tire. Once the tire was installed I pointed out that the brace rod need to be installed. That's when I walked away to gather my taxi crew. I did my normal pre-taxi walkaround; and found nothing out of the ordinary. I climb into the cockpit to ride the brakes; and the plane was pushed out of the hangar. We performed a wet motor and an idle leak check of #2 engine. Then the aircraft was pushed into position to taxi out to the run-up blocks. There were no abnormalities on the taxi out to the blocks. We did our maintenance run out at the blocks and everything was normal also. After the maintenance run we had to taxi from run-up blocks at the north end of airport to the hardstand at the south end of the field with no incident. After taxiing the aircraft to the hardstand I did the post-taxi walkaround everything was normal. I removed the logbook and brought it back to the hangar office to finish the paperwork. There was a logbook entry for the #2 brake leaking. None of the mechanics that worked on the #2 brake replacement held an airworthiness release signature authority/authorized for this type aircraft but they had all done work on this type aircraft for several years. Including brake changes. So; one of the mechanics that was assigned to this aircraft signed off the work on the log page as 'work performed by;' and I signed the airworthiness release block for the work that was performed.

Narrative: ON FEB/SAT/07; I WAS ASKED TO TAKE ACFT X OUT FOR A MAINT RUN. THE ENG BUILD UP SHOP HAD JUST CHANGED THE FUEL FLOW GOVERNOR ON THE #2 ENG. I WALKED INTO XXX TO CHK ON THE PROGRESS OF THE WORK. THE MECHS THAT WERE ASSIGNED TO ACFT X WERE CHANGING THE #2 BRAKE. THEY WERE HAVING DIFFICULTIES INSTALLING THE TIRE; SO I HELPED THEM INSTALL THE TIRE. ONCE THE TIRE WAS INSTALLED I POINTED OUT THAT THE BRACE ROD NEED TO BE INSTALLED. THAT'S WHEN I WALKED AWAY TO GATHER MY TAXI CREW. I DID MY NORMAL PRE-TAXI WALKAROUND; AND FOUND NOTHING OUT OF THE ORDINARY. I CLB INTO THE COCKPIT TO RIDE THE BRAKES; AND THE PLANE WAS PUSHED OUT OF THE HANGAR. WE PERFORMED A WET MOTOR AND AN IDLE LEAK CHK OF #2 ENG. THEN THE ACFT WAS PUSHED INTO POS TO TAXI OUT TO THE RUN-UP BLOCKS. THERE WERE NO ABNORMALITIES ON THE TAXI OUT TO THE BLOCKS. WE DID OUR MAINT RUN OUT AT THE BLOCKS AND EVERYTHING WAS NORMAL ALSO. AFTER THE MAINT RUN WE HAD TO TAXI FROM RUN-UP BLOCKS AT THE N END OF ARPT TO THE HARDSTAND AT THE S END OF THE FIELD WITH NO INCIDENT. AFTER TAXIING THE ACFT TO THE HARDSTAND I DID THE POST-TAXI WALKAROUND EVERYTHING WAS NORMAL. I REMOVED THE LOGBOOK AND BROUGHT IT BACK TO THE HANGAR OFFICE TO FINISH THE PAPERWORK. THERE WAS A LOGBOOK ENTRY FOR THE #2 BRAKE LEAKING. NONE OF THE MECHS THAT WORKED ON THE #2 BRAKE REPLACEMENT HELD AN AIRWORTHINESS RELEASE SIGNATURE AUTH FOR THIS TYPE ACFT BUT THEY HAD ALL DONE WORK ON THIS TYPE ACFT FOR SEVERAL YEARS. INCLUDING BRAKE CHANGES. SO; ONE OF THE MECHS THAT WAS ASSIGNED TO THIS ACFT SIGNED OFF THE WORK ON THE LOG PAGE AS 'WORK PERFORMED BY;' AND I SIGNED THE AIRWORTHINESS RELEASE BLOCK FOR THE WORK THAT WAS PERFORMED.
