(2) Within 36 months after the effective 

date of this AD, replace all H–11 steel barrel 

nuts with new Inconel barrel nuts. 

(ii) If no H–11 steel barrel nut is found at 

all attachment point locations, no further 

work is required by this paragraph. 

(h) Exception to Service Information 

Specifications 

Where Boeing Alert Service Bulletin 767– 

53A0261, dated August 12, 2014, specifies a 

compliance time ‘‘after the Original Issue 

date of this Service Bulletin,’’ this AD 

requires compliance within the specified 

compliance time after the effective date of 

this AD. 

(i) Parts Installation Prohibition 

As of the effective date of this AD, no 

person may install an H–11 steel barrel nut 

on the vertical stabilizer of any airplane. 

(j) Alternative Methods of Compliance 

(AMOCs) 

(1) The Manager, Seattle Aircraft 

Certification Office (ACO), FAA, has the 

authority to approve AMOCs for this AD, if 

requested using the procedures found in 14 

CFR 39.19. In accordance with 14 CFR 39.19, 

send your request to your principal inspector 

or local Flight Standards District Office, as 

appropriate. If sending information directly 

to the manager of the ACO, send it to the 

attention of the person identified in 

paragraph (k)(1) of this AD. Information may 

be emailed to: 9-ANM-Seattle-ACO-AMOCRequests@faa.gov. 

(2) Before using any approved AMOC, 

notify your appropriate principal inspector, 

or lacking a principal inspector, the manager 

of the local flight standards district office/

certificate holding district office. 

(3) An AMOC that provides an acceptable 

level of safety may be used for any repair 

required by this AD if it is approved by the 

Boeing Commercial Airplanes Organization 

Designation Authorization (ODA) that has 

been authorized by the Manager, Seattle 

ACO, to make those findings. For a repair 

method to be approved, the repair must meet 

the certification basis of the airplane, and the 

approval must specifically refer to this AD. 

(4) If any service information contains 

steps that are identified as RC, those steps 

must be done to comply with this AD; any 

steps that are not identified as RC are 

recommended. Those steps that are not 

identified as RC may be deviated from using 

accepted methods in accordance with the 

operator’s maintenance or inspection 

program without obtaining approval of an 

AMOC, provided the steps identified as RC 

can be done and the airplane can be put back 

in a serviceable condition. Any substitutions 

or changes to steps identified as RC require 

approval of an AMOC.

Background 

The FAA has been asked to provide 

two legal interpretations regarding the 

application of 14 CFR 121.521. 

Specifically, both interpretation 

requests present scenarios involving 

supplemental all-cargo part 121 

operations that contain at least one 

international segment and make an 

election, under 14 CFR 121.513, to 

operate under the flight time limitations 

of § 121.515 and §§ 121.521 through 

121.525. 

Both scenarios involve, in part, at 

least one segment in which the aircraft 

would be flown by a flightcrew 

consisting solely of two pilots and no 

other flight crewmembers. Both

2 14 CFR 121.521(a) (emphasis added). 

3Letter to Timothy Slater from Rebecca 

MacPherson, Assistant Chief Counsel for 

Regulations (Sept. 7, 2012) (answer to Question 1). 

interpretation requests then ask the FAA 

to determine which specific flight, duty, 

and rest regulations would apply to 

these scenarios. Accordingly, the FAA 

must determine whether 14 CFR 

121.521 applies to a flightcrew 

consisting solely of two pilots. For the 

reasons discussed below, the FAA 

proposes to find that § 121.521 does not 

apply to any flight segment that is flown 

by a flightcrew consisting only of two 

pilots and no other flight crewmembers. 

Discussion of the Proposal 

Normally, air carriers conducting allcargo supplemental operations under 

part 121 must operate pursuant to the 

flight, duty, and rest provisions of 

§§ 121.503 through 121.509. However, 

supplemental air carriers conducting 

overseas and international all-cargo 

operations may elect, pursuant to 

§ 121.513, to comply with the flight time 

limitations of § 121.515 and §§ 121.521 

through 121.525 (commonly referred to 

as the ‘‘international rules’’).1

Section 121.521 governs the smallestsize flightcrew that can operate under 

these international rules. The regulatory 

text of § 121.521 unambiguously states 

that this section applies only to a ‘‘crew 

of two pilots and at least one additional 

flight crewmember.’’ 2 Thus, the plain 

text of § 121.521 states that there must 

be at least three flight crewmembers in 

order for § 121.521 to apply: (1) two 

pilots; and (2) at least one additional 

flight crewmember. The FAA reaffirmed 

this plain-text reading of § 121.521 in a 

2012 interpretation in which it found 

that a flightcrew consisting of three 

pilots would be subject to the provisions 

of § 121.521.3

Because § 121.521 governs the 

smallest-size flightcrew that can operate 

under the international part 121 flight, 

duty, and rest rules for supplemental 

all-cargo operations and because 

§ 121.521 only applies to a flightcrew 

that has at least three flight 

crewmembers, the FAA proposes to find 

that § 121.521 does not apply to a 

flightcrew of only two pilots and no 

other flight crewmembers. Under the 

proposed interpretation and consistent 

with the FAA’s precedent, a flightcrew 

of only two pilots in a supplemental 

part 121 all-cargo operation would be 

subject to the provisions of § 121.503 

and § 121.505, which, among other 

things, apply to a flightcrew consisting 

solely of two pilots.
