United Thursday confirmed it was retesting the altitude indicating systems on seven Boeing 747-400s that had undergone heavy checks at Korean Air's overhaul facility in Busan, Korea, after it was discovered that the equipment used to test the systems was out of calibration. In a brief statement, United said it had voluntarily disclosed to FAA that it was retesting the aircraft and that it had found no issues. United spokespeople could not be reached for further comment.
