Airworthiness Directives; GROB 

Aircraft SE (Type Certificate Previously 

Held by GROB Aircraft AG) Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule; request for 

comments. 

SUMMARY: The FAA is adopting a new 

airworthiness directive (AD) for all 

GROB Aircraft SE (type certificate 

previously held by GROB Aircraft AG) 

(GROB) Model G 115EG airplanes. This 

AD results from mandatory continuing 

airworthiness information (MCAI) 

issued by the aviation authority of 

another country to identify and correct 

an unsafe condition on an aviation 

product. The MCAI identifies the unsafe 

condition as in-flight detachment of a 

rudder actuator hinge bracket. This AD 

requires repairing the support structure 

at the attachment to the attachment 

bolts on certain flight control surfaces, 

inspecting the support structure at the 

attachment bolts of all flight control 

surfaces, and taking corrective actions if 

discrepancies are detected. The FAA is 

issuing this AD to address the unsafe 

condition on these products. 

DATES: This AD is effective March 24, 

2022. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in this AD 

as of March 24, 2022. 

The FAA must receive comments on 

this AD by April 25, 2022.

Background 

The European Union Aviation Safety 

Agency (EASA), which is the Technical 

Agent for the Member States of the 

European Union, has issued EASA 

Emergency AD 2021–0057–E, dated 

February 26, 2021 (referred to after this 

as ‘‘the MCAI’’), to address the unsafe 

condition on GROB Model G 115E and 

G 115EG airplanes. The MCAI states: 

An occurrence has been reported of inflight detachment of a rudder actuator hinge 

bracket. Subsequent inspection revealed that 

the attaching bolts penetrated the supporting 

structure to such an extent that the structure 

was no longer capable to withstand the loads. 

Penetrating attaching bolts cannot easily be 

detected. The same bolts are also on all other 

control surface hinge brackets. 

This condition, if not detected and 

corrected, could lead to failure or detachment 

of a control surface, possibly resulting in loss 

of control of the aeroplane. 

To address this potential unsafe condition, 

Grob published the [service bulletin] SB 

providing inspection and repair instructions. 

For the reasons described above, this 

[EASA] AD requires a one-time inspection of 

the attachment of all flight control surfaces, 

and, depending on findings, accomplishment 

of applicable corrective action(s). This 

[EASA] AD also requires the reporting of 

inspection results. 

This [EASA] AD is considered an interim 

action and further AD action may follow. 

You may examine the MCAI in the 

AD docket at https://

www.regulations.gov by searching for 

and locating Docket No. FAA–2022– 

0152. 

Related Service Information Under 1 

CFR Part 51 

The FAA reviewed GROB Aircraft 

Service Bulletin MSB1078–205/5, dated 

October 5, 2021. This service 

information specifies performing visual 

and x-ray inspections of the support 

structure at the attachment bolts of all 

flight control surfaces and taking 

corrective actions if discrepancies are 

detected. This service information also 

specifies repairing the support structure 

at the attachment bolts on certain flight 

control surfaces as terminating action 

for the inspection. 

The FAA also reviewed the following 

repair instructions, which contain repair 

instructions for certain attachment point 

positions: 

• GROB Aircraft Repair Instruction 

No. RI–1078–92/1, dated June 2, 2021 

(rudder and vertical stabiliser hinge 

bracket attachment points); 

• GROB Aircraft Repair Instruction 

No. RI–1078–93/1, dated June 2, 2021 

(flaps hinge bracket attachment points); 

• GROB Aircraft Repair Instruction 

No. RI–1078–94/1, dated June 2, 2021 

(aileron hinge bracket attachment 

points); 

• GROB Aircraft Repair Instruction 

No. RI–1078–95/1, dated June 2, 2021 

(elevator and horizontal stabilizer hinge 

bracket attachment points); and 

• GROB Aircraft Repair Instruction 

No. RI–1078–97/1, dated June 2, 2021 

(aileron and flap bellcrank hinge bracket 

attachment points). 

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. 

FAA’s Determination 

This product has been approved by 

the aviation authority of another 

country, and is 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 and service 

information referenced above. The FAA 


jspears on DSK121TN23PROD with RULES1
Federal Register / Vol. 87, No. 46 / Wednesday, March 9, 2022 / Rules and Regulations 13137 

is issuing this AD because it has 

determined the unsafe condition 

described previously is likely to exist or 

develop on other products of the same 

type design. 

AD Requirements 

This AD requires accomplishing the 

actions specified in the service 

information already described, except as 

discussed under ‘‘Differences Between 

this AD and the MCAI.’’ 

Differences Between This AD and the 

MCAI 

The MCAI applies to the Model G 

115E airplane, and this AD does not 

because it does not have an FAA type 

certificate. The MCAI requires an 

inspection and repair if discrepancies 

are found. For bolts in some control 

positions, this AD requires a repair 

before further flight without doing the 

inspection. The MCAI requires using 

GROB Aircraft Service Bulletin 

MSB1078–205/1, dated February 26, 

2021, while this AD requires using the 

revised service information issued after 

the MCAI. The MCAI requires reporting 

the results of the inspection to GROB 

Aircraft SE, but this AD does not. 

Interim Action 

The MCAI was issued as interim 

action as a one-time inspection to 

address an immediate safety of flight 

issue. If EASA takes additional AD 

action, the FAA will evaluate and 

consider further rulemaking. 

Justification for Immediate Adoption 

and Determination of the Effective Date 

Section 553(b)(3)(B) of the 

Administrative Procedure Act (APA) (5 

U.S.C. 551 et seq.) authorizes agencies 

to dispense with notice and comment 

procedures for rules when the agency, 

for ‘‘good cause,’’ finds that those 

procedures are ‘‘impracticable, 

unnecessary, or contrary to the public 

interest.’’ Under this section, an agency, 

upon finding good cause, may issue a 

final rule without providing notice and 

seeking comment prior to issuance. 

Further, section 553(d) of the APA 

authorizes agencies to make rules 

effective in less than thirty days, upon 

a finding of good cause. 

The FAA has found that the risk to 

the flying public justifies foregoing 

notice and comment prior to adoption of 

this rule because there are no airplanes 

currently on the U.S. registry and thus, 

it is unlikely that the FAA will receive 

any adverse comments or useful 

information about this AD from U.S. 

operators. Accordingly, notice and 

opportunity for prior public comment 

are unnecessary pursuant to 5 U.S.C. 

553(b)(3)(B). 

In addition, the FAA finds that good 

cause exists pursuant to 5 U.S.C. 553(d) 

for making this amendment effective in 

less than 30 days, for the same reasons 

the FAA found good cause to forego 

notice and comment. 

Costs of Compliance 

There are currently no affected 

airplanes on the U.S. registry. In the 

event an affected airplane becomes a 

U.S.-registered airplane, the following is 

an estimate of the costs to comply with 

this AD. 

The FAA estimates that it would take 

40 work-hours per airplane to comply 

with control surface repair and the 

inspection in this AD. The average labor 

rate is $85 per work-hour. Required 

parts would cost about $1,500 per 

airplane. 

Based on these figures, the FAA 

estimates the cost of this AD to be 

$4,900 per airplane. 

In addition, the FAA estimates that 

repairing the support structure required 

when discrepancies are found during 

the required inspection would take 40 

work-hours at an average labor rate of 

$85 per work-hour. Required parts 

would cost about $1,000 for a total cost 

of $4,400 per airplane. 

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 Flexibility Act 

The requirements of the Regulatory 

Flexibility Act (RFA) do not apply when 

an agency finds good cause pursuant to 

5 U.S.C. 553 to adopt a rule without 

prior notice and comment. Because FAA 

has determined that it has good cause to 

adopt this rule without prior notice and 

comment, RFA analysis is not required. 

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, 

and 

(2) Will not affect intrastate aviation 

in Alaska.

Airworthiness Directives; Viking Air 

Limited (Type Certificate Previously 

Held by Bombardier Inc.) Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: The FAA is adopting a new 

airworthiness directive (AD) for Viking 

Air Limited (type certificate previously 

held by Bombardier Inc.) Model DHC– 

3 airplanes with a certain wing strut 

assembly installed. This 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 

identifies the unsafe condition as fatigue 

damage of the wing struts. This AD 

requires a bolt hole eddy current 

inspection of the lug plate holes, a 

visual and fluorescent dye penetrant 

inspection of the lug fittings, and a 

visual and eddy current surface scan 

inspection of the wing strut assemblies. 

This unsafe condition could lead to 

failure of the wing strut, which could 

result in an in-flight breakup of the 

wing. The FAA is issuing this AD to 

address the unsafe condition on these 

products. 

DATES: This AD is effective April 13, 

2022. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of April 13, 2022.
