ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for 

Diamond Aircraft Industries GmbH 

Models DA40 and DA40F airplanes that 

would supersede AD 2013–24–14, 

which resulted 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 the fatigue 

strength found in the aft main spar not 

ensuring unlimited lifetime structural 

integrity. We are issuing this proposed 

AD to require actions to address the 

unsafe condition on these products and 

to change the compliance time to 

coincide with other regulatory 

requirements. 

DATES: We must receive comments on 

this proposed AD by May 29, 2014.

20828 Federal Register / Vol. 79, No. 71 / Monday, April 14, 2014 / Proposed Rules 

Discussion 

On November 22, 2013, we issued AD 

2013–24–14, Amendment 39–17689 (78 

FR 72568; December 3, 2013). That AD 

required actions intended to address an 

unsafe condition on Diamond Aircraft 

Industries GmbH Models DA40 and 

DA40F airplanes and was based on 

mandatory continuing airworthiness 

information (MCAI) originated by an 

aviation authority of another country. 

The inspections required by AD 

2013–24–13 are tied to calendar time 

and the Major Structural Inspection 

(MSI) identified in Chapter 5 of the 

airplane maintenance manual (AMM). 

This compliance time mirrors the 

mandatory continuing airworthiness 

information (MCAI) issued by the State 

of Design for these products. 

However, U.S. operators are not 

required to comply with the 

requirement to inspect before the next 

MSI since the Limitations in Chapter 4 

of the AMM are mandatory and the MSI 

in Chapter 5 of the AMM is not 

mandatory. 

Relevant Service Information 

Diamond Aircraft Industries GmbH 

has issued Mandatory Service Bulletin 

MSB 40–074, MSB D4–094, and MSB 

F4–028 (co-published as a single 

document), dated May 10, 2013; 

Diamond Aircraft Industries GmbH 

Work Instructions WI–MSB 40–074, 

WI–MSB D4–094, and WI–MSB F4–028, 

(co-published as a single document), 

dated May 10, 2013; and DA 40 Series 

AMM, Chapter Section 05–28–50, 

Section 2 (Cockpit), page 11, Item 31, 

sub-item ‘‘The rear main bulkhead,’’ 

Rev. 7, dated April 1, 2013. 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. 

Costs of Compliance 

We estimate that this proposed AD 

will affect 747 products of U.S. registry. 

We also estimate that it would take 

about 6 work-hours per product to 

comply with the basic requirements of 

this proposed AD. The average labor 

rate is $85 per work-hour. Required 

parts would cost about $100 per 

product. 

Based on these figures, we estimate 

the cost of the proposed AD on U.S. 

operators to be $455,670, or $610 per 

product. 

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 proposed 

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), 

(3) Will not affect intrastate aviation 

in Alaska, and 

(4) 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.

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for certain 

Bombardier, Inc. Model CL–600–2C10 

(Regional Jet Series 700, 701, & 702) 

airplanes, Model CL–600–2D15 

(Regional Jet Series 705) airplanes, 

Model CL–600–2D24 (Regional Jet 

Series 900) airplanes, and Model CL– 

600–2E25 (Regional Jet Series 1000) 

airplanes. This proposed AD was 

prompted by two in-service reports of 

fracture of the rudder pedal tubes 

installed on the pilot-side rudder bar 

assembly. This proposed AD would 

require repetitive inspections for 

cracking and damage of the pilot-side 

rudder pedal tubes, and corrective 

action if necessary. This proposed AD 

would also provide optional terminating 

action for the repetitive inspections. We 

are proposing this AD to detect and 

correct cracked and damaged pilot-side 

rudder pedal tubes, which could result 

in loss of function of the pilot’s rudder 

pedal during flight, takeoff, or landing, 

and could result in reduced 

controllability of the airplane.
