CHAPTER 7 ROTORCRAFT AUTHORIZATIONS AND LIMITATIONS
Section 3 Offshore Instrument Approach Procedures
GENERAL. This section contains information and guidance to
be used by principal operations inspectors (POI) for the review and approval
of offshore instrument approach procedures. These procedures are to be used
by instrument flight rules (IFR) approved helicopter operators in an offshore
environment to conduct instrument approaches to rigs, platforms or ships that
are at least 5 nautical miles (NM) offshore in uncontrolled airspace. The helicopter
operator will use the airborne radar approaches (ARA) or the offshore standard
approach procedures (OSAP) for conducting instrument approaches in this environment.
APPROACH APPROVAL PROCEDURES. The latest edition of Advisory
(AC) 90-80, Approval of Offshore Helicopter Approaches, contains approval
guidance, procedures criteria, and a sample training program for offshore instrument
approaches. ARA procedures are special instrument approach procedures approved
under the provisions of Federal Aviation Administration (FAA) Order 8260.19,
Flight Procedures and Airspace, latest edition, and FAA Order
States (U.S.) Standards for Terminal Instrument Procedures (TERPS), latest edition.
ARA Approval Procedures. POIs should refer to
AC 90-80, which contains one method of approval criteria and a sample training
program for ARAs. POIs should also note and adhere to the following ARA approval
The regional flight inspection and procedures (FIP) staff is responsible
for the development and approval of ARAs.
A copy of the proposed ARA procedures shall be forwarded for review to
the flight inspection field office (FIFO) that maintains geographic responsibility
for the area in which the ARA will be conducted.
The Flight Standards District Office (FSDO) with geographic responsibility
for the area in which the ARA will be conducted is responsible for the verification
of controlling obstacles.
The certificate-holding district office (CHDO) is responsible for approving
the operatorís use of the en route and instrument approach procedures based
on demonstration of acceptable performance. The CHDO may need the support of
the office having geographic responsibility to observe these demonstrations.
ARAs are documented on FAA Form 8260-7, Special Instrument Approach Procedures.
The FIP staff should amend the ARA with a pen-and-ink change for minor
changes of rig location, provided the en route egress point and procedure name
remain the same and the controlling obstacle does not change; otherwise, the
FIP staff shall develop a new procedure.
Approval Process for OSAPs. Helicopter operators that are
approved for IFR offshore operations and that desire to conduct OSAPs must do
The operator must submit a written request to the CHDO, according to
The POI shall evaluate and test the procedures contained in the request
for OSAP approval, according to
AC 90-80. The FSDO must approve the operatorís OSAP maintenance and training
programs before issuing authorization.
The POI shall utilize Part H112 of the operations specifications (OpSpecs)
to authorize Title 14 of the Code of Federal Regulations
(14 CFR) part 135 operators to conduct OSAPs. For
14 CFR part 91 operations, the FSDO shall issue a letter of authorization
to each part
91 operator. A sample letter of authorization is contained in Appendix 5
Paragraphs 4-1118 through 4-1124.
