| Departure airport: |

| Flightnumber: |
1808 |
Narrative:
Flight 1808 took off from Boston runway 4L at 21:30 for a flight
to Auburn. Clearance was received of 7000 feet and to contact
Portland Approach Control.
Portland Approach cleared Flight 1808 at 21:58 for a runway 4
ILS approach. Three minutes later the controller noticed that
Flight 1808 was east of course and asked if the it was receiving
the Lewiston localizer. The captain replied that they hadn't and
were given instructions to turn left heading 340. A left turn to
354deg started and the aircraft passed Lewie Outer Marker (LOM)
at 165 knots, 2600 feet (30 knots too fast and 600 feet too
high). At 22:02 the aircraft exited the left side of the
localizer, still at a 354deg heading. The crew then tried to
capture the glide slope and enter the localizer again until it
entered the left side of the localizer (22:04:08) and descended
through the bottom boundary of the glide slope. At ca 22:04:16
the aircraft struck trees 4007 feet short of the runway and 440
feet right of the extended centreline, continued 737 feet and
struck level ground in nearly an inverted attitude.
PROBABLE CAUSE: "The captain's continuation of an unstabilized
approach which resulted in a descent below glide slope.
Contributing to the unstabilized approach was the radar
controller's issuance and the captain's acceptance of a
non-standard air traffic control radar vector resulting in an
excessive intercept with the localizer."
