Douglas DC 9 twin engine jetliner, operating as a scheduled domestic passenger flight from Burlington, Vermont to Logan International Airport in Boston, Massachusetts, with an intermediate stop in Manchester, New Hampshire. 1 On July 3. AM, while on an ILSinstrument approach into Logan in low clouds and fog, the aircraft descended below the glidepath, struck a seawall with a landing gear and crashed, killing all but two of its 8. Both survivors later died of their injuries. Aircraft and creweditThe DC 9 3. N9. 75. NE,2 serial number 4. September 1. 96. 7 and had 1. The jetliner was one of the aircraft that Delta Air Lines acquired in their 1. Northeast Airlines, to whom the aircraft was originally delivered. The flight crew consisted of Captain John Streil 4. First Officer Sidney Burrill 3. Captain Streil, a highly experienced pilot, had accumulated roughly 1. He had 1. 7 years experience as pilot in command and had been flying DC 9s since 1. First Officer Burrill was also an experienced airman, with just under 7,0. Occupying the cockpit jumpseat was a third pilot, Joseph Burrell 5. DC 9. 3Accident sequenceedit.

The aircraft, flying at 3,0. Bostons approach control to intercept the final approach course to the ILS runway 4. R approach at a 4. As it was later revealed, the controller was busy handling a potential collision conflict between two other aircraft, and therefore neglected to clear Flight 7. The flight crew had to ask the controller for approach clearance, which was immediately given, but by that time more than a minute after the intercept vector had been issued they were high and fast and almost over the outer marker. The flight crew subsequently failed to stabilize the aircrafts descent rate and airspeed, descended below the glideslope and drifted away from the localizer course, hitting a seawall about 1. The aircraft was destroyed, killing 8. One of the two survivors died after two hours, and the other, Leopold Chouinard, died of burn injuries on December 1. Chouinard is not listed as a Delta 7. Code of Federal Regulations7 that defines a fatality as taking place within 3. The weather conditions at the time of the crash were partial obscuration and fog, with a ceiling of 4. Runway visual range RVR was 1,4. Investigationedit. Flight 7. 23 descent profile, showing actual glide path flown red, vs. The NTSB investigated the accident and was able to retrieve both the CVR and FDR. The investigators concluded that, based on the retrieved flight data and simulations, the flight crew very likely operated the flight director improperly, inadvertently switching it into a go around mode during the final approach, instead of the appropriate approach mode. This caused confusion and additional pressure, and contributed to the unstablized approach and deviation from the glide path. 1 According to the CVR, no altitude callouts were made by the crew during the final approach, as the aircraft descended below the glideslope and decision height, until it struck the seawall and crashed. 5The board determined the following Probable Cause for the accident 5. The unstabilized nature of the approach was due initially to the aircrafts passing the outer marker above the glide slope at an excessive airspeed and thereafter compounded by the flightcrews preoccupation with the questionable information presented by the flight director system. The poor positioning of the flight for the approach was in part the result of nonstandard air traffic control services. See alsoeditAsiana Airlines Flight 2. China Airlines Flight 1.
