Series 200, Jetstream Series 3101, and 

Jetstream Model 3201 Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for the 

products listed above. This proposed 

AD results from 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: 

As a result of fatigue-testing programme on 

Jetstream aeroplanes, cracks have been found 

on the main landing gear (MLG) fittings that 

embody modifications JM5218 or JM8003. 

This condition, if not detected and 

corrected, could lead to a MLG collapse on 

the ground or during landing, possibly 

resulting in a fuel tank rupture, consequent 

damage to the aeroplane or injury to the 

occupants. 

The proposed AD would require actions 

that are intended to address the unsafe 

condition described in the MCAI. 

DATES: We must receive comments on 

this proposed AD by May 2, 2011. 

ADDRESSES: You may send comments by 

any of the following methods:

Discussion 

The European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Community, has issued AD No. 2011– 

0016, dated February 1, 2011 (referred 

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

an unsafe condition for the specified 

products.. The MCAI states: 

As a result of fatigue-testing programme on 

Jetstream aeroplanes, cracks have been found 

on the main landing gear (MLG) fittings that 

embody modifications JM5218 or JM8003. 

This condition, if not detected and 

corrected, could lead to a MLG collapse on 

the ground or during landing, possibly 

resulting in a fuel tank rupture, consequent 

damage to the aeroplane or injury to the 

occupants. 

Analysis of this failure indicates that an 

inspection regime has to be implemented in 

order to ensure the safe operation of the MLG 

beyond the accumulation of 41,000 Flight 

Cycles (FC). 

For the reasons described above, this AD 

requires initial and repetitive eddy current 

inspections, and depending on findings, 

accomplishment of corrective actions. 

The MCAI requires replacing or 

repairing any cracked MLG fitting found 

during the initial and repetitive 

inspections. You may obtain further 

information by examining the MCAI in 

the AD docket. 

Relevant Service Information 

BAE Systems has issued British 

Aerospace Jetstream Series 3100 & 3200 

Service Bulletin 32–JA090240, Revision 

1, dated January 18, 2010. The actions 

described in this service information are 

intended to correct the unsafe condition 

identified in the MCAI. 

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. 

Differences Between This Proposed AD 

and the MCAI or Service Information 

We have reviewed the MCAI and 

related service information and, in 

general, agree with their substance. But 

we might have found it necessary to use 

different words from those in the MCAI 

to ensure the AD is clear for U.S. 

operators and is enforceable. In making 

these changes, we do not intend to differ 

substantively from the information 

provided in the MCAI and related 

service information. 

We might also have proposed 

different actions in this AD from those 

in the MCAI in order to follow FAA 

policies. Any such differences are 

highlighted in a NOTE within the 

proposed AD.

14350 Federal Register / Vol. 76, No. 51 / Wednesday, March 16, 2011 / Proposed Rules 

Costs of Compliance 

We estimate that this proposed AD 

will affect 190 products of U.S. registry. 

We also estimate that it would take 

about 20 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 $323,000 or $1,700 per 

product. 

In addition, we estimate that any 

necessary follow-on actions would take 

about 4 work-hours and require parts 

costing $8,000, for a cost of $8,340 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); and 

3. 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. 

We prepared a regulatory evaluation 

of the estimated costs to comply with 

this proposed AD and placed it in the 

AD docket.

The Proposed Amendment 

Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA proposes to amend 14 CFR part 

39 as follows: 

PART 39—AIRWORTHINESS 

DIRECTIVES 

1. The authority citation for part 39 

continues to read as follows: 

Authority: 49 U.S.C. 106(g), 40113, 44701. 

§ 39.13 [Amended] 

2. The FAA amends § 39.13 by adding 

the following new AD: 

British Aerospace Regional Aircraft: Docket 

No. FAA–2011–0230; Directorate 

Identifier 2011–CE–004–AD. 

Comments Due Date 

(a) We must receive comments by May 2, 

2011. 

Affected ADs 

(b) None. 

Applicability 

(c) This AD applies to British Aerospace 

Regional Aircraft Model HP.137 Jetstream 

Mk.1, Jetstream Series 200, Jetstream Series 

3101, and Jetstream Model 3201 airplanes, all 

serial numbers, that are: 

(1) Equipped with main landing gear 

(MLG) fittings, part number (P/N) 

1379133B1/B2/B3/B4 that incorporate 

Modifications JM5218 or JM8003; and 

(2) certificated in any category. 

Subject 

(d) Air Transport Association of America 

(ATA) Code 32: Landing Gear. 

Reason 

(e) The mandatory continuing 

airworthiness information (MCAI) states: 

As a result of fatigue-testing programme on 

Jetstream aeroplanes, cracks have been found 

on the main landing gear (MLG) fittings that 

embody modifications JM5218 or JM8003. 

This condition, if not detected and 

corrected, could lead to a MLG collapse on 

the ground or during landing, possibly 

resulting in a fuel tank rupture, consequent 

damage to the aeroplane or injury to the 

occupants. 

Analysis of this failure indicates that an 

inspection regime has to be implemented in 

order to ensure the safe operation of the MLG 

beyond the accumulation of 41,000 Flight 

Cycles (FC). 

For the reasons described above, this AD 

requires initial and repetitive eddy current 

inspections, and depending on findings, 

accomplishment of corrective actions. 

The MCAI requires replacing or repairing any 

cracked MLG fitting found during the initial 

and repetitive inspections. You may obtain 

further information by examining the MCAI 

in the AD docket. 

Actions and Compliance 

(f) Unless already done, do the following 

actions: 

(1) Upon accumulating 41,000 flight cycles 

(landings) on the MLG since first installation 

or within the next 2,000 flight cycles 

(landings) on the MLG after the effective date 

of this AD, whichever occurs later, eddy 

current inspect all the MLG leg pivot beam 

fastener bores for cracks. Do the inspections 

following British Aerospace Jetstream Series 

3100 & 3200 Service Bulletin 32–JA090240, 

Revision 1, dated January 18, 2010. 

(2) Before further flight after any inspection 

required in paragraphs (f)(1), (f)(2)(i), and 

(f)(2)(ii) of this AD in which cracks are found, 

replace the MLG fitting or repair any cracks. 

Cracks are defined in paragraph 2.D.(4) of 

British Aerospace Jetstream Series 3100 & 

3200 Service Bulletin 32–JA090240, Revision 

1, dated January 18, 2010. Replace or repair 

the MLG fitting following British Aerospace 

Jetstream Series 3100 & 3200 Service Bulletin 

32–JA090240, Revision 1, dated January 18, 

2010. Any time the MLG fitting is repaired 

or replaced, do the following actions as 

applicable: 

(i) MLG fitting is replaced with a new MLG 

fitting as specified in paragraph (f)(2) of this 

AD: Upon accumulating 41,000 flight cycles 

(landings) after replacement, eddy current 

inspect all the MLG leg pivot beam fastener 

bores for cracks. Do the inspections following 

British Aerospace Jetstream Series 3100 & 

3200 Service Bulletin 32–JA090240, Revision 

1, dated January 18, 2010. 

(ii) MGL fitting is repaired as specified in 

paragraph (f)(2) of this AD: Upon 

accumulating 27,000 flight cycles (landings) 

after the last repair and repetitively thereafter 

at intervals not to exceed 27,000 flight cycles 

(landings), eddy current inspect all the MLG 

leg pivot beam fastener bores for cracks. Do 

the inspections following British Aerospace 

Jetstream Series 3100 & 3200 Service Bulletin 

32–JA090240, Revision 1, dated January 18, 

2010. 

(3) If no cracks are found during any 

inspection required in paragraph (f)(1), 

(f)(2)(i), or (f)(2)(ii) of this AD, repetitively 

thereafter upon accumulating 27,000 flight 

cycles (landings) after the last inspection, 

eddy current inspect all the MLG leg pivot 

beam fastener bores for cracks. 

(4) As of the effective date of this AD, only 

install a MLG fitting specified in paragraph 

(c)(1) of this AD that has been eddy current 

inspected and found free of cracks following 

British Aerospace Jetstream Series 3100 & 

3200 Service Bulletin 32–JA090240, Revision 

1, dated January 18, 2010. 

(5) The compliance times of this AD are 

presented in flight cycles (landings). If the 

total flight cycles have not been kept, 

multiply the total number of airplane hours 

time-in-service by 0.75. For the purposes of 

this AD: 

(1) 75 cycles equals 100 hours TIS; and 

(2) 750 cycles equals 1,000 hours TIS.
