SUMMARY: The FAA is adopting a new 

airworthiness directive (AD) for all 

British Aerospace (Operations) Limited 

Model Jetstream Model 3101 airplanes 

and British Aerospace Regional Aircraft 

Model Jetstream Model 3201 airplanes. 

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 identifies 

the unsafe condition as stress corrosion 

cracking of the primary flight control 

cable terminals. This AD requires 

repetitively inspecting the turnbuckle 

type control cable terminals in the 

rudder and elevator primary flight 

control circuits for corrosion, pitting, 

and cracking and, depending on the 

inspection results, replacing an affected 

cable assembly. The FAA is issuing this 

AD to address the unsafe condition on 

these products. 

DATES: This AD is effective July 13, 

2022.

SUPPLEMENTARY INFORMATION: 

Background 

The FAA issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 by adding an AD that would 

apply to all British Aerospace 

(Operations) Limited Model Jetstream 

Model 3101 and British Aerospace 

Regional Aircraft Model Jetstream 

Model 3201 airplanes. The NPRM 

published in the Federal Register on 

March 22, 2022 (87 FR 16118). The 

NPRM was prompted by MCAI 

originated by the Civil Aviation 

Authority (CAA), which is the aviation 

authority for the United Kingdom. CAA 

has issued AD G–2021–0017, dated 

December 21, 2021 (referred to after this 

as ‘‘the MCAI’’), to correct an unsafe 

condition on all BAE Systems 

(Operations) Limited Model Jetstream 

Series 3100 and Series 3200 airplanes. 

The MCAI states: 

There were reports of cable terminal 

failures on a variety of civil aircraft types 

(which did not include the Jetstream 3100 & 

3200 series aircraft). These reports were 

initially made in the USA, Australia & New 

Zealand. Subsequent investigations 

identified that the failed terminals were 

made from the same material specification; 

MS21260, which calls up materials 

SAE303Se or SAE304 stainless steel. It is 

understood that these corrosion resistant 

steels are susceptible to Stress Corrosion 

Cracking (SCC) in service when subject to 

contamination. 

BAE Systems (Operations) Ltd recognises 

that SAE 303Se and 304 stainless steels are 

used in the primary flight control cable 

terminal of the Jetstream 3100 & 3200 series 

aircraft. 

The Jetstream 3100 & 3200 series aircraft 

feature a single path for the elevator and 

rudder primary control cable circuits. For the 

elevator circuit, a potential unsafe condition 

exists if an elevator cable terminal fails at any 

point in the primary elevator system aft of 

the dual flight controls in the cockpit, 

because this would result in a loss of primary 

elevator control. This is only considered 

unsafe during take-off after V1, where 

sufficient runway may not be available to 

brake the aircraft, or during an approach 

where there is insufficient altitude to recover 

control of the aircraft using the aircraft’s 

elevator trim controls. 

For the rudder circuit, a potential unsafe 

condition exists if a rudder cable terminal 

fails at any point in the primary rudder 

system aft of the dual flight controls in the 

cockpit, because this would result in a loss 

of primary rudder control. This is only 

considered unsafe when landing in strong 

crosswinds or after an engine failure during 

take-off and initial climb, where vertical axis 

(yaw) control cannot be maintained using 

rudder trim or asymmetrical power. 

You may examine the MCAI in the 

AD docket at https://

www.regulations.gov by searching for 

and locating Docket No. FAA–2022– 

0285. 

In the NPRM, the FAA proposed to 

require repetitively inspecting the 

turnbuckle type control cable terminals 

in the rudder and elevator primary flight 

control circuits for corrosion, pitting, 

and cracking and, depending on the 

inspection results, replacing an affected 

cable assembly. The FAA is issuing this 

AD to address the unsafe condition on 

these products.

Discussion of Final Airworthiness 

Directive 

Comments 

The FAA received no comments on 

the NPRM or on the determination of 

the costs. 

Conclusion 

These products have been approved 

by the aviation authority of another 

country and are approved for operation 

in the United States. Pursuant to the 

FAA’s bilateral agreement with this 

State of Design Authority, it has notified 

the FAA of the unsafe condition 

described in the MCAI referenced 

above. The FAA reviewed the relevant 

data and determined that air safety and 

the public interest require adopting this 

AD as proposed. Accordingly, the FAA 

is issuing this AD to address the unsafe 

condition on these products. This AD is 

adopted as proposed in the NPRM. 

Related Service Information Under 1 

CFR Part 51 

The FAA reviewed British Aerospace 

Jetstream Series 3100 & 3200 Service 

Bulletin 27–JA181040, Original Issue, 

dated January 17, 2019. This service 

information specifies procedures for 

repetitively inspecting all threaded 

turnbuckle type control cable end 

terminals on certain part-numbered 

rudder and elevator primary flight 

control circuits for signs of corrosion, 

pitting, and cracking on the terminal 

fitting, and specifies replacing an 

affected cable assembly when the 

inspection results require it. 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. 

Differences Between This AD and the 

MCAI 

The MCAI and service information 

apply to Model Jetstream Series 3100 

and Jetstream Series 3200 airplanes, 

which are identified on the FAA type 

certificates as Jetstream Model 3101 

airplanes and Jetstream Model 3201 

airplanes, respectively. 

Although the service information 

specifies reporting inspection results to 

the manufacturer, this AD does not 

require that action. 

Costs of Compliance 

The FAA estimates that this AD 

affects 18 airplanes of U.S. registry. 

The FAA estimates the following 

costs to comply with this AD: 

ESTIMATED COSTS

Action Labor cost Parts cost Cost per airplane Cost on U.S. 

operators 

Inspection ......... 4 work-hours × $85 per hour = 

$340.

Not applicable ... $340 per inspection cycle ............ $6,120 per inspection cycle. 

The FAA estimates the following 

costs to replace a cable assembly based 

on the results of the inspection. The 

FAA has no way of determining the 

number of airplanes that might need 

this action: 

ON-CONDITION COSTS

Action Labor cost Parts cost Cost per 

airplane 

Replacement of cable assembly .................................. 10 work-hours × $85 per hour = $850 ......................... $5,000 $5,850 

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. 

The FAA is 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 

This AD will not have federalism 

implications under Executive Order 

13132. This AD will 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 that this AD: 

(1) Is not a ‘‘significant regulatory 

action’’ under Executive Order 12866, 

(2) Will not affect intrastate aviation 

in Alaska, 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.

originated by an aviation authority of another 

country to identify and correct an unsafe 

condition on an aviation product. The MCAI 

identifies the unsafe condition as stress 

corrosion cracking of the primary flight 

control cable terminal. The FAA is issuing 

this AD to detect and correct corrosion, 

pitting, or cracking in the primary flight 

control cable terminals. The unsafe 

condition, if not addressed, could result in 

failure of the primary flight control cable 

terminal and loss of airplane control. 

(f) Compliance 

Comply with this AD within the 

compliance times specified, unless already 

done. 

(g) Required Actions 

(1) Before any primary rudder or primary 

elevator flight control circuit cable 

accumulates 16 years since first installation 

on an airplane or within 12 months after the 

effective date of this AD, whichever occurs 

later, and thereafter at intervals not to exceed 

24 months, inspect all threaded turnbuckle 

type control cable terminals for signs of 

corrosion, pitting, and cracking by following 

paragraph (2) in Section 2.B. Part 1 and 

Section 2.B. Part 2 of the Accomplishment 

Instructions in British Aerospace Jetstream 

Series 3100 & 3200 Service Bulletin 27– 

JA181040, Original Issue, dated January 17, 

2019 (SB 27–JA181040). If the age of any 

primary rudder or primary elevator flight 

control circuit cable is unknown, do the 

inspection within 12 months after the 

effective date of this AD and thereafter at 

intervals not to exceed 24 months. 

(2) If, during any inspection required by 

paragraph (g)(1) of this AD, there is pitting 

or cracking or corrosion that exceeds 

minimum damage limits, before further 

flight, replace the affected cable assembly 

with a new (zero hours time-in-service) cable 

assembly. 

(3) Replacing a cable assembly does not 

terminate the inspections required by this 

AD. After replacing a cable assembly, do the 

inspection in paragraph (g)(1) of this AD 

before the cable assembly accumulates 15 

years since first installation on an airplane 

and thereafter at intervals not to exceed 24 

months.
