In rare cases, it may happen that a TCDS is only designed for specific serial numbers of an aircraft.
This is illustrated by the Piper PA-28-181:
The EASA TCDS "EASA.IM.A.234" applies to the following serial numbers:
- 2890206 to 2890231
For all older Piper PA-28-181 there still applies LBA TCDS 518a.
Another similar case occurs when a national data sheet is used instead of the EASA TCDS.
ASA-AMOffice© maintains exactly one data sheet for an aircraft, so you must do the following if you want to assign an alternative TCDS to your aircraft:
- Enter the alternative number of your aircraft
- Remove the selections "Allow takeover a TDCS numbers" and "Check and correct (if necessary) TCDS numbers of all positions automatically"
Thus, the modified TCDS is not automatically changed by ASA-AMOffice©.
