Détails:
The Airbus struck pole-mounted electrical transmission cables on Nimitz Hill during a localizer approach to runway 06L at Guam in IMC. The aircraft executed a missed approach and landed safely at Guam. After arriving back at Manila the aircraft was inspected and found to have minor damage to the fuselage and landing gear. On August 6, 1997 an accident happened on the same hill when a Korean Air Boeing 747-3B5 collided with terrain while on approaching runway 06L. The MSAW (minimum safe altitude warning) software which was not functioning properly in 1997 was working fine this time. But the CERAP controller, who was no longer in direct communication with PAL110, did not advise the Agana tower controller of the warning. The warning was displayed in the control tower as well, however, the display was logged as out of service because of damage from a typhoon that struck Guam nine days earlier, and its operation was not verified as reliable.

PROBABLE CAUSE: "The pilot's initiation of a premature descent that was both below the nominal glideslope and steeper than normal. Contributing to the incident was the air traffic controller's failure to respond to the MSAW warning and issue a safety alert as required by FAA order."

languages:

Issued: 11-JUL-2006	To: FAA	A-06-044
Redesign the minimum safe altitude warning (MSAW) and conflict alert systems and alerting methods such that they reliably capture and direct controller attention to potentially hazardous situations detected by the systems. Implement software changes at all air traffic control facilities providing MSAW and conflict alert services. (Open - Acceptable Response)
Issued: 11-JUL-2006	To: FAA	A-06-045
Implement any software and adaptation modifications needed to minimize or eliminate unwarranted minimum safe altitude warning alerts. (Open - Acceptable Response)
Issued: 11-JUL-2006	To: FAA	A-06-046
Perform a technical and procedural review at all air traffic facilities with minimum safe altitude warning (MSAW) or conflict alert capability to verify that software configuration and parameters are consistent with local air traffic procedures. Ensure that MSAW and conflict alert warnings are provided to the relevant controllers. (Closed - Reconsidered)
Issued: 11-JUL-2006	To: FAA	A-06-047
Amend FAA Order 3120.4L, Air Traffic Technical Training, to require that all controllers study and demonstrate an understanding of the relationship between charted minimum instrument flight rules altitudes and the underlying topography for their areas. Emphasize that controllers should maintain awareness of aircraft altitudes to detect and effectively react to situations in which a safety alert may prevent an accident (especially aircraft operating in remote areas at night).
