A supplemental type certificate (STC) is a type certificate (TC) issued when an applicant has received FAA approval to modify an aircraft from its original design. The STC, which incorporates by reference the related TC, approves not only the modification but also how that modification affects the original design. The following is alisting of ASIG STC's:

STC # Design Data Description FAA-PMA Install Kit P/Ns

FAA-PMA approved parts are elligible for instalaltion in a given aircraft or type as a modification or OEM replacement component. The following is a list of ASIG's non-kitted FAA-PMA direct-replacement parts:

ASIG Part# PMA Description Eligibility
1011-9000-00 Cable Assembly, EGT [superceeds Boeing p/n(s): D51A56107 and -3] DC-8-70 series aircraft
1065-5001-00 Trolley, Skytender Beverage  SEE ABOVE  for STCs ST09859AC (FAA) and 10060645 (EASA)

A Technical Standard Order Authorization, or TSOA, is an approval that authorizes a manufacturer to produce a material, part or appliances to a TSO standard. Receiving a TSO authorization is both design and production approval. The following is a list of ASIG's FAA TSO approved parts:

FAA TSO# TSO Description ASIG P/N Eligibility
TSO-C115c Required Navigation Performance (RNP) Equipment Using Multi-Sensor Inputs - This approval is specific to ASIG's flyTab XFB Aircraft Interface Module (INCOMPLETE SYSTEM); see part number eligibility next column. 1048-5002-00
TSO-C175 Galley Carts, Containers and Associated Components - This approval is specific to ASIG's SkyTender Beverage Trolley Model 0100; see part number eligibility next column. 1065-5000-00(_) 

Installation Kits

Aircraft parts are approved by the FAA. Not by the OEM, not by the aircraft manufacturer and not by parts distributors! Parts can be approved as a part of the Type Certification, if it's on the aircraft when the airplane is approved. Parts can also be approved through PMA (Parts Manufacturing Approval); these parts are designed and manufactured by a company with an FAA-approved Fabrication Inspection System and subsequently added to that company's approval list as a supplement. Parts manufactured by independent suppliers and OEMs sold through any outlet other than the aircraft manufacturer are PMA'd prior to distribution.

Regardless of the manufacturer, all FAA-PMA parts are subject to the scrutiny and certification standards of 14 CFR §21. All ASIG FAA-PMA parts meet stringent FAA airworthiness requirements. ASIG qualifies our parts via two basic methods and in one of four different ways of classification, the critical distinction being the identicality and non-identicality status of the PMA.

Classic & Contemporary aircraft face a myriad of challenges in terms of maintaining systems dispatch reliability and operating performance. These DC-8-7X Exhaust Gas Temperature "pigtail" harnesses ensure the on-time and safe performance of your re-engined DC-8 aircraft by improving upon legacy design technologies increasing in-service durability. Using modern metallurgy and casting processes as well as space-grade rated conductors, ASIG's EGT thermocouple harnesses provide exceptional value, availability and performance in excess of legacy OEM replacements. OEM part numbers D51A56107-3 & D51A56107-5 can be quickly, safely, easily and efficiently replaced with these modern high quality components. These units are manufactured under FAA-PMA No. PQ1052SW.

PMA Facts:

1. There is no statistical evidence from either the FAA or EASA representing safety concerns with PMA components.

2. Today it is an economic imperative for airlines and other operators to minimize maintenance costs through the savings and reliability improvements offered by PMA parts (when compared to OEM catalogue pricing and MTBF (Meat Time Between Failure) rates.

3. Airframe OEMs exploit federal regulations to develop "micro-nopolies" into the designs of their aircraft in order to maximize their profits throughout the lifecycle of their airframes. This is achieved by artificially inflating the cost of continued airworthiness to owner and operators in the purchase of replacement parts.

4. Genuine FAA-PMA parts, like the ones developed and manufactured by ASIG, take advantage of improvements in raw materials and processes in their designs allowing modern solutions, which are superior in reliability and affordability, to high-failure OEM designs of the 1990's and prior.
