AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for the 

products listed above. This AD results 

from mandatory continuing 

airworthiness information (MCAI) 

issued 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: 

A stub axle failure of the main landing gear 

on a Dornier 228–200 aeroplane was reported 

to RUAG Aerospace. Investigations revealed 

that the fracture of the axle—manufacturer 

Part Number (P/N) A–511000B28B was due 

to fatigue. Already in the year 1993 two 

failures of P/N A–511000B28B axles 

occurred. Those events led in 1994 the 

Luftfahrt-Bundesamt—Germany’s National 

Aviation Authority—to publish 

Airworthiness Directive (AD) D–1994–042 to 

mandate the replacement of A–511000B28B 

axles by improved-design axle with P/N A– 

511000C28B (Dornier Luftfahrt GmbH 

Service bulletin 228–214). 

It is believed that a misinterpretation of the 

Dornier 228 repair/maintenance 

documentation caused inadvertent 

installation of A–511000B28B axle on the 

accident aeroplane’s main landing gear with 

P/N A–511000C00F. This configuration was 

not approved for installation and was 

therefore not addressed by LBA AD D–1994– 

042 or Dornier SB–228–214. 

The actions specified in this Airworthiness 

Directive are intended to prevent main 

landing gear failure, which could result in 

loss of control of the aeroplane during 

landing operations. 

We are issuing this AD to require 

actions to correct the unsafe condition 

on these products. 

DATES: This AD becomes effective 

November 3, 2009. 

On November 3, 2009, the Director of 

the Federal Register approved the 

incorporation by reference of certain 

publications listed in this AD.

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to include an AD that would 

apply to the specified products. That 

NPRM was published in the Federal 

Register on June 25, 2009 (74 FR 30247). 

That NPRM proposed to correct an 

unsafe condition for the specified 

products. The MCAI states: 

A stub axle failure of the main landing gear 

on a Dornier 228–200 aeroplane was reported 

to RUAG Aerospace. Investigations revealed 

that the fracture of the axle—manufacturer 

Part Number (P/N) A–511000B28B was due 

to fatigue. Already in the year 1993 two 

failures of P/N A–511000B28B axles 

occurred. Those events led in 1994 the 

Luftfahrt-Bundesamt—Germany’s National 

Aviation Authority—to publish 

Airworthiness Directive (AD) D–1994–042 to 

mandate the replacement of A–511000B28B 

axles by improved-design axle with P/N 

A–511000C28B (Dornier Luftfahrt GmbH 

Service bulletin 228–214). 

It is believed that a misinterpretation of the 

Dornier 228 repair/maintenance 

documentation caused inadvertent 


CPrice-Sewell on DSKGBLS3C1PROD with RULES
49802 Federal Register / Vol. 74, No. 187 / Tuesday, September 29, 2009 / Rules and Regulations 

installation of A–511000B28B axle on the 

accident aeroplane’s main landing gear with 

P/N A–511000C00F. This configuration was 

not approved for installation and was 

therefore not addressed by LBA AD D–1994– 

042 or Dornier SB–228–214. 

The actions specified in this Airworthiness 

Directive are intended to prevent main 

landing gear failure, which could result in 

loss of control of the aeroplane during 

landing operations. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

received no comments on the NPRM or 

on the determination of the cost to the 

public. 

Conclusion 

We reviewed the available data and 

determined that air safety and the 

public interest require adopting the AD 

as proposed. 

Differences Between This 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 required 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 AD. 

Costs of Compliance 

We estimate that this AD will affect 

15 products of U.S. registry. We also 

estimate that it would take about 1 

work-hour per product to comply with 

the basic requirements of this AD. The 

average labor rate is $80 per work-hour. 

Based on these figures, we estimate 

the cost of this AD on U.S. operators to 

be $1,200 or $80 per product. 

In addition, we estimate that any 

necessary follow-on actions would take 

about 16 work-hours and require parts 

costing $23,734, for a cost of $25,014 

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 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 this AD: 

(1) Is not a ‘‘significant regulatory 

action’’ under Executive Order 12866; 

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

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 AD and placed it in the AD Docket. 

Examining the AD Docket 

You may examine the AD docket on 

the Internet at http:// 

www.regulations.gov; or in person at the 

Docket Management Facility between 9 

a.m. and 5 p.m., Monday through 

Friday, except Federal holidays. The AD 

docket contains the NPRM, the 

regulatory evaluation, any comments 

received, and other information. The 

street address for the Docket Office 

(telephone (800) 647–5527) is in the 

ADDRESSES section. Comments will be 

available in the AD docket shortly after 

receipt.

Adoption of the Amendment 

■ Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA amends 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: 

2009–20–07 Dornier Luftfahrt GmbH: 

Amendment 39–16030; Docket No. 

FAA–2009–0574; Directorate Identifier 

2009–CE–028–AD. 

Effective Date 

(a) This airworthiness directive (AD) 

becomes effective November 3, 2009. 

Affected ADs 

(b) None. 

Applicability 

(c) This AD applies to Models Dornier 228– 

100, Dornier 228–101, Dornier 228–200, 

Dornier 228–201, and Dornier 228–202 

airplanes, all serial numbers, 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: 

A stub axle failure of the main landing gear 

on a Dornier 228–200 aeroplane was reported 

to RUAG Aerospace. Investigations revealed 

that the fracture of the axle—manufacturer 

Part Number (P/N) A–511000B28B was due 

to fatigue. Already in the year 1993 two 

failures of P/N A–511000B28B axles 

occurred. Those events led in 1994 the 

Luftfahrt-Bundesamt—Germany’s National 

Aviation Authority—to publish 

Airworthiness Directive (AD) D–1994–042 to 

mandate the replacement of A–511000B28B 

axles by improved-design axle with P/N 

A–511000C28B (Dornier Luftfahrt GmbH 

Service bulletin 228–214). 

It is believed that a misinterpretation of the 

Dornier 228 repair/maintenance 

documentation caused inadvertent 

installation of A–511000B28B axle on the 

accident aeroplane’s main landing gear with 

P/N A–511000C00F. This configuration was 

not approved for installation and was 

therefore not addressed by LBA AD D–1994– 

042 or Dornier SB–228–214. 

The actions specified in this Airworthiness 

Directive are intended to prevent main 

landing gear failure, which could result in 

loss of control of the aeroplane during 

landing operations. 

The MCAI requires inspection of the main 

landing gear (MLG) and, if applicable, 

replacement of the MLG stub axle. 

Actions and Compliance 

(f) Unless already done, do the following 

actions following RUAG Aerospace Defence 

Technology Dornier 228 Service Bulletin SB– 

228–276, dated October 16, 2008: 


CPrice-Sewell on DSKGBLS3C1PROD with RULES
Federal Register / Vol. 74, No. 187 / Tuesday, September 29, 2009 / Rules and Regulations 49803 

(1) Within the next 14 days after November 

3, 2009 (the effective date of this AD), inspect 

the main landing gear (MLG) stub axle. 

(2) If any P/N A–511000B28B stub axle is 

found, before accumulation of 9,500 total 

landings on the axle, or before further flight 

if total landings on the axle exceed 9,500 

total landings on November 3, 2009 (the 

effective date of this AD), replace the axle or 

the housing assembly with a new axle P/N 

A–511000C28B. If the total number of 

landings accumulated by the stub axle cannot 

be positively determined, the stub axle must 

be considered to have accumulated more 

than 9,500 total landings. 

(3) Operators that do not have landing (or 

cycle) records may determine the number of 

landings (or cycles) by dividing the number 

of hours time-in-service of each airplane by 

the time of the average flight for the aircraft 

of that type in the operator’s fleet. 

Note 1: P/N A–511000C28B axle together 

with the housings P/N A–511000C27B and 

P/N A–521000C27B form the Axle 

Assemblies P/N AD511010A00C and P/N 

AD521010A00C, which are life limited to 

48,000 landings per the Dornier 228 Time 

Limits/Maintenance Checks Manual 

(TLMCM) Chapter 05–10–10. 

(4) As of November 3, 2009 (the effective 

date of this AD), do not install MLG 

assemblies P/N A–511000C00F and P/N A– 

521000C00F fitted with a P/N A– 

511000B28B stub axle on any airplane.

SUMMARY: We are adopting a new 

airworthiness directive (AD) for the 

products listed above. 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 describes the unsafe 

condition as: 

The Elevator control bearing stand RU19 

was required to be inspected for correct 

production in 1978 in accordance with 

Technical Note (TN) No.301/6. In 2009, an 

accident occurred with a DG–100. The 

suspension bolt was found torn out of the 

bearing stand making the elevator 

uncontrollable. The investigation confirmed 

that the bearing stand had not been produced 

correctly. It is therefore assumed that the 

inspections per TN 301/6 did not produce 

reliable results. 

This AD requires actions that are 

intended to address the unsafe 

condition described in the MCAI. 

DATES: This AD becomes effective 

October 19, 2009. 

On October 19, 2009 the Director of 

the Federal Register approved the 

incorporation by reference of certain 

publications listed in this AD. 

We must receive comments on this 

AD by November 13, 2009.
