National Airlines 727 Crashes Into AtlanticBy Patrick Mondout
On May 8, 1978 at about 9:20 p.m., a National Airlines 727 with 52
passengers and 6 crew crashed into Escambia Bay on approach to the
Pensacola Airport. Three of the passengers drowned while awaiting rescue.
The National Transportation Safety Board determined the probable cause
of this accident was the flightcrew's unprofessionally conducted
nonprecision instrument approach; the captain and the crew failed to
monitor the descent rate and altitude, and the first officer failed to
provide the captain with required altitude and approach performance
callouts (each 100 feet below 500 should have been verbally acknowledged).
The crew failed to check and utilize all instruments available for
altitude awareness, turned off the ground proximity warning system, and
failed to configure the aircraft properly and in a timely manner for the
approach.

Contributing to the accident was the radar controller's failure to provide
advance notice of the start-descent point which accelerated the pace of
the crew's cockpit activities after the passage of the final approach fix
.
At 920:15, the ground proximity warning system (GPWS) whooper sounded,
and the " Pull up, pull up" voice warning from the 727 began.
The GPWS warning continued until 9:20:24. During this nine second period
only two remarks appeared on the CVR transcript: At 9:20:19, Captain
George Kunz said "Did you (get) your thing", and at 9:20:21,
First Officer (F/O) Leonard Sanderson said, "Descent rate's keeping
it up."
Flight Engineer (F/E) James Stockwell stated that he turned off the
GPWS and that he did this in response to what he believed was Captain
Kunz's command to turn the system off. He also testified that he believed
at the time the aircraft was still above 1,000 feet.

At 9:20:31, F/O Sanderson said, "I... we're down to fifty
feet." Two seconds later, the aircraft hit the water.
Captain Kunz said that he misread his altimeter at 500 feet and
believed he saw 1,500 feet. He stated that "When that figure got on
my mind as I ran my scan after that, I was seeing 400 and 300 and they
were 14(00) and 13(00) in my mind. I was looking at the needle
instead of looking at the 1,000-foot marker in it. I didn't actually look
at the thousand-foot pointer at that time. I just glanced down at the
hundred- foot pointer.'' (See figure on right.)
F/O Sanderson said that he failed to make the required altitude
callouts, because he was never aware of the fact that the aircraft was
below 1,000 feet until just before impact.
