Narrative:

An MTR was handed off on approach to runway 1L at andrews on a course coincident with the ILS final. On initial contact with adw radar, the MTR was cleared for the approach approximately 20 mi final. 7-10 mi later, dca and adw approach noticed the MTR veered off the final to the west. The computer recordings which were plotted showed the aircraft crossed the airspace boundary by .4 mi. The boundary is 1 mi west of the final approach course. There should be a wider buffer for protecting the final approach course for the ILS at adw.

Title: MTR PENETRATED ADJACENT FAC AIRSPACE WITHOUT APPROVAL.

Narrative: AN MTR WAS HANDED OFF ON APCH TO RWY 1L AT ANDREWS ON A COURSE COINCIDENT WITH THE ILS FINAL. ON INITIAL CONTACT WITH ADW RADAR, THE MTR WAS CLRED FOR THE APCH APPROX 20 MI FINAL. 7-10 MI LATER, DCA AND ADW APCH NOTICED THE MTR VEERED OFF THE FINAL TO THE W. THE COMPUTER RECORDINGS WHICH WERE PLOTTED SHOWED THE ACFT CROSSED THE AIRSPACE BOUNDARY BY .4 MI. THE BOUNDARY IS 1 MI W OF THE FINAL APCH COURSE. THERE SHOULD BE A WIDER BUFFER FOR PROTECTING THE FINAL APCH COURSE FOR THE ILS AT ADW.
