status(es) listed and not applicable to additional status(es) within the TDR-94/94D

or additional status(es) within the equipment family.

NOTE: Installation of units modified in accordance with this service bulletin may require

a change to the aircraft TC/STC data unless the new equipment part number is

already included in the data.

B. Concurrent Requirements

Service Bulletins 21, 24 and 29 must be installed prior to or at the same time as this

service bulletin.

C. Reason

(1) Condition Modification Affects

The -007, -008, -207, -308 and -309 units do not have ADS-B capability.

(2) Extent Condition Encountered

All -007, -008, -207, -308, and -309 units requiring ADS-B capability.

3-Dec 5/11 Page 3
Service Bulletin

(4) Expected Benefits of Modification

Converted units will have ADS-B capability. For the -007 and -008, units will add

GAMA Label 102G “Selected Altitude” Compatibility. For the -008, -308, units, the SB

provides the proper transition of Mode S capability during ground to air transition.

D. Description

For the -007/207 units, the CPU I/O card is replaced. On the -008/308/309 units, software

is updated, a jumper wire is removed, and a capacitor is added to video processor circuit

card A6. The identification plate is changed on all units to reflect the new part number.

E. Compliance

Optional.

F. Approval

TDR-94 (CPN 622-9352-409) conforms to FAA TSO C112 Class 3A2 121 010, C166a

Class A3 - Transmitting Only.

TDR-94D (CPN 622-9210-409) conforms to FAA TSO C112 Class 3A2 121 011, C166a

Class A3 XMT Only.

Installation of this service bulletin changes the part number of the TDR-94/94D as listed

in paragraph 1.A. Installation of units modified in accordance with this service bulletin

may require a change to aircraft TC/STC data unless the new part number is already

included in the data.

G. Labor

Estimated: 2.5 labor hours for installation and testing.

H. Weight and Balance

Not affected.

I. Electrical Load Data

Not affected.
