This deviation memorandum supersedes AIR600-19-6C0-DM116, dated May 09 2019,
authorizing a policy change to FAA Order 8130.2, Airworthiness Certification of Aircraft
allowing the use of the Aviation Safety Knowledge Management Environment (ASKME)
AWC application tool. AWC is an electronic tool that automates the application for, and
issuance of airworthiness certificates. The tool is now available for use throughout the
FAA, general public and industry. Additionally, electronic signature technology has been
incorporated into AWC relieving the requirement for permanent ink signature on related
airworthiness documents.
The primary audience for this memo is Aircraft Certification Service (AIR) Aviation
Safety Inspectors (ASI), Flight Standards Service (AFS) airworthiness ASIs, all DMIR,
DAR-F and DAR-T, Organization Designation Authorization (ODA) administrators and
manufacturing Organization Management Team (OMT) members, FAA Academy
Instructors, and general public applicants.

This notice updates policy associated with Master Minimum
Equipment List (MMEL) Policy Letter (PL)-109, Supplemental Type Certificate (STC) MMEL
Relief Process.

This order provides guidance for all personnel in the approval of facilities for Category (CAT) I
Runway Visual Range (RVR) 1800 at runways with reduced lighting, Special Authorization
(SA) CAT I and all CAT II and CAT III.
With a growing emphasis on performance-based operations, different levels of operation may be
authorized based on the flight equipment of a specific operator and the ground equipment
available at specific runways. While certain ground facility requirements are needed to support
all levels of either CAT I, CAT II, or CAT III operations, a higher category of operations may be
performed on different “types” of ground equipment if the airborne equipment, crew training, or
other factors offset any changes in ground facility requirements. In these situations, operations
are predicated on the use of specific equipment and/or procedures, which will be required in the
operator’s applicable authorization (such as an operations specification (OpSpec), management
specification (MSpec), or Letter of Authorization (LOA)).

This AC provides instructions
for completing Federal Aviation Administration (FAA) Form 337, Major Repair and
Alteration (Airframe, Powerplant, Propeller, or Appliance).
