SUPPLEMENTARY INFORMATION: 

Discussion 

The EASA, which is the Technical 

Agent for the Member States of the 

European Union, has issued EASA AD 

2020–0223, dated October 14, 2020 

(EASA AD 2020–0223) (also referred to 

as the Mandatory Continuing 

Airworthiness Information, or the 

MCAI), to correct an unsafe condition 

for all Saab AB, Support and Services 

Model SAAB 2000 airplanes. 

The FAA issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 by adding an AD that would 

apply to all Saab AB, Support and 

Services Model SAAB 2000 airplanes. 

The NPRM published in the Federal 

Register on February 24, 2021 (86 FR 

11184). The NPRM was prompted by a 

report indicating that the left-hand MLG 

collapsed after touchdown, causing 

severe damage to the airplane. The 


khammond on DSKJM1Z7X2PROD with RULES
33100 Federal Register / Vol. 86, No. 119 / Thursday, June 24, 2021 / Rules and Regulations 

NPRM proposed to require modifying 

the MLG hydraulic transfer valve, as 

specified in EASA AD 2020–0223. 

The FAA is issuing this AD to address 

abnormal behavior of the MLG 

hydraulic transfer valve due to a 

restriction in hydraulic flow, which 

could cause the MLG hydraulic transfer 

valve to not function properly and fail 

to retract, extend, or lock the MLG, and 

possibly result in MLG collapse 

following landing and consequent 

damage to the airplane and injury to 

occupants. See the MCAI for additional 

background information. 

Comments 

The FAA gave the public the 

opportunity to participate in developing 

this final rule. The FAA received no 

comments on the NPRM or on the 

determination of the cost to the public. 

Conclusion 

The FAA reviewed the relevant data 

and determined that air safety and the 

public interest require adopting this 

final rule as proposed, except for minor 

editorial changes. The FAA has 

determined that these minor changes: 

• Are consistent with the intent that 

was proposed in the NPRM for 

addressing the unsafe condition; and 

• Do not add any additional burden 

upon the public than was already 

proposed in the NPRM. 

Related Service Information Under 1 

CFR Part 51 

EASA AD 2020–0223 describes 

procedures for modifying the MLG 

hydraulic transfer valve. This 

modification includes installing a new 

relay, relocation of wiring, and 

installation of new wiring, to ensure 

that, when the emergency extension 

handle is used, the transfer valve 

solenoid is energized to force the 

transfer valve to the ‘‘gear down’’ 

position. This material 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. 

Costs of Compliance 

The FAA estimates that this AD 

affects 8 airplanes of U.S. registry. The 

FAA estimates the following costs to 

comply with this AD: 

ESTIMATED COSTS FOR REQUIRED ACTIONS

Labor cost Parts cost Cost per 

product 

Cost on U.S. 

operators 

20 work-hours × $85 per hour = $1,700 ..................................................................................... $1,875 $3,575 $28,600

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.

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 The Boeing Company Model 

737–100, –200, –200C, –300, –400, and 

–500 series airplanes. The NPRM 

published in the Federal Register on 

February 24, 2021 (86 FR 11186). The 

NPRM was prompted by a report 

indicating that a crack was found on the 

splice angle flange that is attached to the 

STA 540 bulkhead in the area between

bulkhead splice angle for any cracking, 

and applicable on-condition actions. 

The FAA is issuing this AD to address 

any cracking in the splice angle, which 

could result in the inability of a 

principal structural element to sustain 

limit load and could adversely affect the 

structural integrity of the airplane; in 

addition, such cracking could lead to
