1)    Maintenance: 3356.
2)    Avionics: 5356.

B.    Safety Assurance System (SAS). For Title 14 of the Code of Federal Regulations (14 CFR) parts 121 and 135, use SAS automation and the associated Data Collection Tools (DCT).

2-217    OBJECTIVE. This section provides guidance for evaluating an applicant’s refueling procedures and facilities.

2-218    GENERAL.

Indicates new/changed information.

A.    Applicant’s Procedures. If applicable by rule, an applicant must have procedures as required by part 121, § 121.135(b)(19); part 125, § 125.73(j); and part 135, § 135.23(j). The following must be included as components of the applicant’s manual:

Indicates new/changed information.

    Refueling procedures,

    Protection from fire (including electrostatic protection procedures),

    Procedures for eliminating fuel contamination procedures, and

    Supervising and protecting passengers during refueling procedures.

Indicates new/changed information. Indicates new/changed information.

B.    Applicant’s Manual. The applicant’s manuals must include procedures for vendors andcontractors. Title 14 CFR part 139 issues airport operating certificates to airports to establish standards for fueling facilities, but this does not relieve the applicant of overall responsibility for conducting those operations within established industry standards (refer to https://www.faa.gov/airports/airport_safety/part139_cert/faqs/#fueling).

2-219    FUELS.

A.    Aviation Gasoline (AVGAS). The naming system for the grades of aviation gasoline is derived from the general term “AVGAS” followed by the grade marking. The grades are identified by their performance numbers, as recognized by all military and commercial specifications (e.g., 80, 100LL, and 100).

1)    The naming system for AVGAS grades is printed on all containers in white letters and numbers on a red background.
2)    Storage containers are also marked with a circular band around the piping, the color of which matches the dye in the AVGAS flowing through the line. The dyes are red for AVGAS 80, blue for AVGAS 100LL, and green for AVGAS 100. A minimum 4-inch-wide band is recommended. If the pipeline is painted the color of the AVGAS, then no banding is needed.

B.    Jet Fuels. The classifications of aviation turbine fuels are universally referred to as jet fuels.

1)    The naming system for the jet fuel is printed on all containers in white letters on a black background to distinguish it from AVGAS.
2)    Examples of jet fuel storage container markings include the following:

    Jet A fuel containers are marked with a single 4-inch-wide (minimum) black band around the piping;

    Jet A-1 fuel containers are marked with two 4-inch-wide (minimum) black bands; and

    Jet B-1 fuel containers are marked with three 4-inch-wide (minimum) yellow bands.

2-220    GEOGRAPHIC CONSIDERATIONS. Inspections of contract fueling facilities by the office having the geographic responsibility must be coordinated with the certificate-holding district office (CHDO).

Indicates new/changed information.

2-221    REVIEWING THE MANUAL. Maintenance aviation safety inspectors (ASI) of part 121 certificate holders must also determine whether the applicant’s manual contains appropriate instructions for storage and dispensing of aviation fuels.

2-222    INSPECTING THE FACILITIES. The Maintenance ASIs are responsible for ensuring that the applicant’s facilities comply with the manual procedures and established industry standards. For contracted services, it is still the applicant’s responsibility to ensure adherence to its manual procedures and standards.

2-223    COORDINATION REQUIREMENTS. This task requires coordination with the applicant.
