SERVICE BULLETIN TITLE NAVIGATION - ENHANCED SURVEILLANCE TRANSPONDER STRAPPING MODIFICATION

Transcription

1 TITLE NAVIGATION - ENHANCED SURVEILLANCE TRANSPONDER STRAPPING MODIFICATION EFFECTIVITY MODEL SERIAL NUMBERS 525B (CJ3) thru -0056, thru -0262, and thru equipped with TCAS I NOTE: This service bulletin does not apply to airplanes equipped with TCAS II. TCAS II equipped airplanes respond correctly when interrogated by ground stations. REASON Some ATC ground stations use the CA field (transponder capability) to determine if the transponder is capable of Elementary or Enhanced Surveillance. On airplanes equipped with TCAS I the TDR-94/94D transponders will respond to the interrogation with a zero in the CA field. The zero in the CA field will not allow the ground station to further interrogate the transponder for Elementary or Enhanced Surveillance data, making the airplane appear to be incapable of transmitting Elementary or Enhanced Surveillance data. DESCRIPTION This service bulletin provides parts and instructions to add a ground to one of the pins on the TDR-94/94D transponders that will allow a proper response from the transponders when interrogated. COMPLIANCE DISCRETIONARY. This service bulletin can be accomplished at the discretion of the owner. A service bulletin published by Cessna Aircraft Company may be recorded as completed in an aircraft log only when the following requirements are satisfied: 1) The mechanic must complete all of the instructions in the service bulletin, including the intent therein. 2) The mechanic must correctly use and install all applicable parts supplied with the service bulletin kit. Only with written authorization from Cessna Aircraft Company can substitute parts or rebuilt parts be used to replace new parts. 3) The mechanic or airplane owner must use the technical data in the service bulletin only as approved and published. 4) The mechanic or airplane owner must apply the information in the service bulletin only to aircraft serial numbers identified in the Effectivity section of the bulletin. 5) The mechanic or airplane owner must use maintenance practices that are identified as acceptable standard practices in the aviation industry and governmental regulations. No individual or corporate organization other than Cessna Aircraft Company is authorized to make or apply any changes to a Cessna-issued service bulletin, service letter, or flight manual supplement without prior written consent from Cessna Aircraft Company. Cessna Aircraft Company is not responsible for the quality of maintenance performed to comply with this document, unless the maintenance is accomplished at a Cessna-owned Citation Service Center.
