THE PILOT OF A CESSNA 170 LOST DIRECTIONAL CONTROL AND GROUND LOOPED WHILE TAXIING FOR TAKE OFF. THE FAA CONTROL TOWER HAD INSTRUCTED THE PILOT TO TAXI BEHIND A TAXIING B-727, AND ISSUED CAUTION: WAKE TURBULENCE. THE IDLE POWER OF THE B-727 CAUSED THE CESSNA 170 PILOT TO LOSE CONTROL. THE LEFT WING OF THE CESSNA WAS LIFTED INTO THE AIR. THE AIRCRAFT CAME TO REST ON ITS NOSE AND LEFT WING.
THE PLT REPORTED THAT DURING ARRIVAL, HE CHECKED THE WINDSOCK & NOTED A X-WIND CONDITION OF 10 KTS OR LESS. HOWEVER, HE SAID THE WINDSOCK WAS BEING BLOWN FROM SIDE TO SIDE. WHILE LANDING ON RWY 26, THE ACFT VEERED TO THE RIGHT. SUBSEQUENTLY, THE LEFT GEAR FAILED. THE PLT REPORTED THAT THE WIND WAS GUSTY.
These match the airframe or engine model. Whether each one applies, and whether it's been complied with, depends on serial numbers, equipment and logbook entries. Applicability must be confirmed by a mechanic against the aircraft's records.
