ABNORMAL ENGINE INSTRUMENT INDICATIONS

The AFM/POH for the specific airplane contains information
that should be followed in the event of any
abnormal engine instrument indications. The table on
the next page offers generic information on some of
the more commonly experienced in-flight abnormal
engine instrument indications, their possible causes,
and corrective actions. [Table 1]

DOOR OPENING IN FLIGHT

In most instances, the occurrence of an inadvertent
door opening is not of great concern to the safety of a
flight, but rather, the pilot's reaction at the moment the
incident happens. A door opening in flight may be
accompanied by a sudden loud noise, sustained noise
level and possible vibration or buffeting. If a pilot
allows himself or herself to become distracted to the
point where attention is focused on the open door
rather than maintaining control of the airplane, loss of
control may result, even though disruption of airflow
by the door is minimal.

In the event of an inadvertent door opening in flight or
on takeoff, the pilot should adhere to the following.

• Concentrate on flying the airplane. Particularly in
light single- and twin-engine airplanes; a cabin
door that opens in flight seldom if ever compromises
the airplane's ability to fly. There may be
some handling effects such as roll and/or yaw, but
in most instances these can be easily overcome.
• If the door opens after lift-off, do not rush to land.
Climb to normal traffic pattern altitude, fly a normal
traffic pattern, and make a normal landing.

• Do not release the seat belt and shoulder harness
in an attempt to reach the door. Leave the door
alone. Land as soon as practicable, and close the
door once safely on the ground.
• Remember that most doors will not stay wide
open. They will usually bang open, then settle
partly closed. A slip towards the door may cause
it to open wider; a slip away from the door may
push it closed.
• Do not panic. Try to ignore the unfamiliar noise
and vibration. Also, do not rush. Attempting to
get the airplane on the ground as quickly as possible
may result in steep turns at low altitude.
• Complete all items on the landing checklist.
• Remember that accidents are almost never
caused by an open door. Rather, an open door
accident is caused by the pilot's distraction or
failure to maintain control of the airplane.

INADVERTENT VFR FLIGHT INTO IMC GENERAL

It is beyond the scope of this handbook to incorporate
a course of training in basic attitude instrument
flying. This information is contained in FAA-H-
8083-15, Instrument Flying Handbook. Certain
pilot certificates and/or associated ratings require
training in instrument flying and a demonstration of
specific instrument flying tasks on the practical test.
