ASDF’s in-flight refueling plane damaged  during checkup at base
NAGOYA, May 21 KYODO
 An in-flight refueling airplane sustained damage and  was unable to fly in early March during a checkup shortly after it was deployed  in late February as Japan’s first plane of its kind at an Air Self-Defense Force  base in Komaki, Aichi Prefecture, base officials said Wednesday.
The  engine covers on both wings of the KC-767 tanker were damaged March 5 as leading  edge flaps on the wings suddenly lowered when a worker was checking the plane in  a hangar at the base.
An ASDF member who was in the cockpit said the  slats lowered after the electrical system for the slats suddenly came on when  the officer was replacing an electric bulb for the hydraulic pump switch, they  said.
The base suspects there was some operation error behind the  incident.
Two KC-767s, jets developed based on the Boeing 767, have been  deployed at the base and were involved in test flights. They are scheduled to be  put into full operation in late fiscal 2009, which ends in March  2010.
In-flight refueling planes help to extend the flight range of  fighters.
