Mechanical Instrument Replacement

Approval is granted to replace legacy mechanical instrumentation as

follows:

• Installation of the AV-30-C (Dedicated AI mode) as the primary

source for attitude and slip. Installation replaces the existing stand-

alone vacuum or electrically powered attitude indicator.

• Installation of the AV-30-C (Dedicated DG mode) as the primary

source for direction-of-flight. Installation replaces the existing stand-

alone vacuum or electrically powered non-slaved directional gyro

indicator.

Note that when installed as a DG, a reversionary AI is available for display.

This functionality is supplemental only and does not satisfy requirements

for a backup or standby attitude, turn and slip, or turn coordinator.

7.2

Approval is granted to install the AV-30-C as a non-required instrument,

augmenting existing required instrumentation. In this configuration, the

AV-30-C must not replace an existing required instrument.

7.3

The aircraft's vacuum system typically may be removed under a field

approval process (FAA Form 337) if no other systems or equipment

requires it. The AV-30-C installation approval does not address this

alteration.
