another country to identify and correct 

an unsafe condition on an aviation 

product. The MCAI describes the unsafe 

condition as missing countersunk 

washers under the head of the main 

landing gear trunnion cap tension bolts 

that could cause fatigue in the bolt 

shanks. We are issuing this proposed 

AD to require actions to address the 

unsafe condition on these products. 

DATES: We must receive comments on 

this proposed AD by July 24, 2015.

Discussion 

The European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Community, has issued AD No.: 2015– 

0061, dated April 20, 2015 (referred to 

after this as ‘‘the MCAI’’), to correct an 

unsafe condition for the specified 

products. The MCAI states: 

The review of the BAE production drawing 

for main landing gear (MLG) fitting 

installation identified a risk of omitting 

installation of a countersunk washer under 

the head of the MLG trunnion cap tension 

bolts, potentially causing fatigue in the bolt 

shank under the head of such tension bolt(s). 

This condition, if not detected and 

corrected, could lead to failure of the bolt(s), 

thereby compromising the structural integrity 

of the other MLG tension bolts holding the 

MLG in place, possibly resulting in collapse 

of the MLG on take-off or landing with 

consequent damage to the aeroplane and 

injury to occupants. 

Although so far, no in-service bolt head 

failures have been reported since entry in to 

service of the type design in 1986, to address 

this potential unsafe condition, BAE Systems 

(Operations) Ltd issued Service Bulletin (SB) 

57–JA120141 to provide inspection 

instructions. 

For the reasons described above, this AD 

requires inspection and, depending on 

findings, replacement of the MLG trunnion 

cap tension bolts. 

You may examine the MCAI on the 

Internet at http://www.regulations.gov 

by searching for and locating Docket No. 

FAA–2015–2048. 

Related Service Information Under 1 

CFR Part 51 

British Aerospace Regional Aircraft 

has issued British Aerospace Jetstream 

Series 3100 & 3200 Service Bulletin 57– 

JA120141, REVISION 1, dated April 8, 

2014. The service information describes 

procedures for inspection and 

replacement of main landing gear 

trunnion cap tension bolts. This service 

information is reasonably available 

because the interested parties have 

access to it through their normal course 

of business or by the means identified 

in the ADDRESSES section of this NPRM. 

FAA’s Determination and Requirements 

of the Proposed AD 

This product has been approved by 

the aviation authority of another 

country, and is approved for operation 

in the United States. Pursuant to our 

bilateral agreement with this State of 

Design Authority, they have notified us 

of the unsafe condition described in the 

MCAI and service information 

referenced above. We are proposing this 

AD because we evaluated all 

information and determined the unsafe 

condition exists and is likely to exist or 

develop on other products of the same 

type design. 

Costs of Compliance 

We estimate that this proposed AD 

will affect 66 products of U.S. registry. 

We also estimate that it would take 

about 6 work-hours per product to 

comply with the basic requirements of 

this proposed AD. The average labor 

rate is $85 per work-hour. 

Based on these figures, we estimate 

the cost of the proposed AD on U.S. 

operators to be $33,660, or $510 per 

product. 

In addition, we estimate that any 

necessary follow-on actions would take 

about 1 work-hour and require parts 

costing $1,200, for a cost of $1,285 per 

product. We have no way of 

determining the number of products 

that may need these actions. 

Authority for This Rulemaking 

Title 49 of the United States Code 

specifies the FAA’s authority to issue 

rules on aviation safety. Subtitle I, 

section 106, describes the authority of 

the FAA Administrator. ‘‘Subtitle VII: 

Aviation Programs,’’ describes in more 

detail the scope of the Agency’s 

authority. 

We are issuing this rulemaking under 

the authority described in ‘‘Subtitle VII, 

Part A, Subpart III, Section 44701: 

General requirements.’’ Under that 

section, Congress charges the FAA with 

promoting safe flight of civil aircraft in 

air commerce by prescribing regulations 

for practices, methods, and procedures 

the Administrator finds necessary for 

safety in air commerce. This regulation 

is within the scope of that authority 

because it addresses an unsafe condition 

that is likely to exist or develop on 

products identified in this rulemaking 

action. 

Regulatory Findings 

We determined that this proposed AD 

would not have federalism implications 

under Executive Order 13132. This 

proposed AD would not have a 

substantial direct effect on the States, on 

the relationship between the national 

Government and the States, or on the 

distribution of power and 

responsibilities among the various 

levels of government. 

For the reasons discussed above, I 

certify this proposed regulation: 

(1) Is not a ‘‘significant regulatory 

action’’ under Executive Order 12866, 

(2) Is not a ‘‘significant rule’’ under 

the DOT Regulatory Policies and 

Procedures (44 FR 11034, February 26, 

1979), 

(3) Will not affect intrastate aviation 

in Alaska, and 

(4) Will not have a significant 

economic impact, positive or negative, 

on a substantial number of small entities 

under the criteria of the Regulatory 

Flexibility Act.

tkelley on DSK3SPTVN1PROD with PROPOSALS
32512 Federal Register / Vol. 80, No. 110 / Tuesday, June 9, 2015 / Proposed Rules 

(e) Reason 

This AD was prompted by mandatory 

continuing airworthiness information (MCAI) 

originated by an aviation authority of another 

country to identify and correct an unsafe 

condition on an aviation product. The MCAI 

describes the unsafe condition as missing 

countersunk washers under the head of the 

main landing gear (MLG) trunnion cap 

tension bolts that could cause fatigue in the 

bolt shanks. We are issuing this AD to detect 

and correct missing countersunk washers, 

which could lead to failure of the bolt(s), 

thereby compromising the structural integrity 

of the other MLG tension bolts holding the 

MLG in place, possibly resulting in collapse 

of the MLG on take-off or landing with 

consequent damage to the airplane and injury 

to occupants. 

(f) Actions and Compliance 

Unless already done, do the actions in 

paragraphs (f)(1) through (f)(4) of this AD, 

including all subparagraphs, following the 

Accomplishment Instructions in British 

Aerospace Jetstream Series 3100 & 3200 

Service Bulletin 57–JA120141, REVISION 1, 

dated April 8, 2014: 

(1) This AD allows credit for the actions 

required in paragraphs (f)(3) and (f)(4), 

including all subparagraphs, of this AD if 

done before the effective date of this AD 

following the Accomplishment Instructions 

of British Aerospace Jetstream Series 3100 & 

3200 Service Bulletin 57–JA120141, Original 

Issue, dated: July 31, 2012. 

(2) For the purposes of this AD, owner/

operators who do not track total flight cycles 

(FC), multiply the total number of airplane 

hours time-in-service by 0.75 to calculate the 

FC. 

(3) For Pre-Mod JM5218 airplanes: Within 

250 FC after the effective date of this AD, do 

a magnetic particle inspection (MPI) of each 

MLG trunnion cap tension bolt. 

(i) If no crack is found during the MPI 

required by paragraph (f)(1) of this AD, before 

further flight, either re-install the crack-free 

bolt(s) or install a replacement bolt(s) having 

the same part number (P/N) as the original 

bolt. Install a countersunk washer under the 

bolt(s) ensuring the washer P/N is applicable 

to the diameter bolt installed as specified in 

figure 1 of paragraph (f)(3)(i) of this AD. 

Bolt P/N Washer P/N 

MS21250H06040 ...... PKS1000–6–2–S 

(washer). 

MS21250H07040 ...... PKS1000–7–2–S 

(washer). 

Figure 1 of paragraph (f)(3)(i)—Pre-Mod 

JM5218 Replacement Parts 

(ii) If a cracked bolt is found during the 

inspection required by paragraph (f)(3) of this 

AD, before further flight, replace each 

cracked bolt with a replacement bolt having 

the same P/N as the original bolt. Install a 

countersunk washer under the bolt ensuring 

the washer P/N is applicable to the diameter 

bolt installed as specified in figure 1 of 

paragraph (f)(3)(i) of this AD. 

(4) For Post-Mod JM5218 airplanes: 

Visually inspect each MLG trunnion cap 

tension bolt to determine which type of bolt 

is installed. 

(i) If it is determined the installed bolts are 

P/N MS21134H07045 or P/N 

MS21134H07059 during the inspection 

required in paragraph (f)(4) of this AD, before 

further flight (except as specified in 

paragraph (f)(4)(i)(A) of this AD), replace 

each ‘old’ bolt P/N with a ‘new’ bolt P/N as 

specified in figure 2 of paragraph (f)(4)(i) of 

this AD and install a washer having P/N 

PKS1000–7–2–S under each bolt. 

Bolt P/N ‘Old’ Bolt P/N ‘New’ 

MS21134H07045 ...... MS21134H07046, or 

MS21250H07046. 

MS21134H07059 ...... MS21134H07060, or 

MS21250H07060. 

Figure 2 of paragraph (f)(4)(i)—Post-Mod 

JM5218 Replacement Parts 

(A) If no ‘new’ replacement bolt is 

available to comply with paragraph (f)(4)(i) of 

this AD, the ‘old’ bolt may be reinstalled 

without a countersunk washer, provided that 

within 500 FC after reinstallation and 

repetitively thereafter at intervals not to 

exceed 500 FC, each affected bolt is 

inspected by MPI. 

(B) Within 2,000 FC after reinstallation of 

a bolt as allowed by paragraph (f)(4)(i)(A) of 

this AD or before further flight if a crack was 

found during any MPI as required by 

paragraph (f)(4)(i)(A) of this AD, whichever 

occurs first, replace the ‘old’ bolt P/N with 

a ‘new’ bolt P/N as specified in figure 2 of 

paragraph (f)(4)(i) of this AD and install a 

washer having P/N PKS1000–7–2–S under 

each bolt. 

(ii) If it is determined the installed bolts are 

P/N MS21250H07046 or P/N 

MS21250H07060 and no countersunk washer 

is installed during the inspection required in 

paragraph (f)(4) of this AD, before further 

flight, do an MPI of each MLG trunnion cap 

tension bolt. 

(A) If no crack is found during the MPI 

required by paragraph (f)(4)(ii) of this AD, 

before further flight, either re-install the 

crack-free bolts or install replacement bolts 

having a ‘new’ bolt P/N as specified in figure 

2 of paragraph (f)(4)(i) of this AD and install 

a countersunk washer P/N PKS1000–7–2–S 

under each bolt. 

(B) If any crack is found during the MPI 

required by paragraph (f)(4)(ii) of this AD, 

before further flight, replace each cracked 

bolt with a serviceable one having a ‘new’ 

bolt P/N as specified in figure 2 of paragraph 

(f)(4)(i) of this AD and install a countersunk 

washer P/N PKS1000–7–2–S under each bolt.
