Background

    We typically issue STCs that permit installation on any aircraft of 
a specific type and model designation. Aircraft compatibility is 
addressed by the following limitation: ``The installer is responsible 
for determining the compatibility of this STC with other previously 
approved modifications.'' Nevertheless there have been installations 
made on inappropriate aircraft. These inappropriate installations could 
have been prevented if STC approvals were restricted to a specified 
baseline aircraft configuration that includes details of the STC 
physical and functional interfaces with the prototype aircraft.
    Applicant's installation drawings or other installation 
instructions have not always been detailed enough for accurate 
replication of the design. This is especially true when follow-on STC 
installations occur at facilities other than that used by the STC 
holder for the prototype installation.
    The STC certification process does not adequately address how to 
evaluate the compatibility of an STC with other previously installed 
STCs, major alterations or repairs. We need a more rigorous 
compatibility evaluation for certain STCs. This proposed policy ensures 
that the modified aircraft will be airworthy.

How To Get Copies
