**Airworthiness Directives; The Boeing Company Model 737–100, –200, –200C,**  **–300, –400, and –500 Series Airplanes**

**AGENCY :**  Federal Aviation Administration (FAA), Department of Transportation (DOT).

**ACTION :**  Notice of proposed rulemaking (NPRM).

**SUMMARY :**  The FAA proposes to supersede an existing airworthiness directive (AD) that applies to all Model 737–100, –200, –200C, –300, –400, and –500 series airplanes. The existing AD currently requires repetitive inspections to find cracks, fractures, or corrosion of each carriage spindle of the left and right outboard mid-flaps, and corrective action if necessary. The existing AD also currently requires repetitive gap checks of the inboard and outboard carriage of the outboard mid-flaps to detect fractured carriage spindles, and corrective actions if necessary. This proposed AD would require any new or serviceable carriage spindle installed per the requirements of the existing AD to meet minimum allowable diameter measurements taken at three locations. This proposed AD also would require new repetitive inspections, measurements, and overhaul of the carriage spindles, and applicable corrective actions. In addition, this proposed AD would require replacing any carriage spindle when it has reached its maximum life limit. This proposed AD results from reports of fractures that resulted from stress corrosion and pitting along the length of the spindle and spindle diameter, and additional reports of corrosion on the outboard flap carriage spindles. We are proposing this AD to detect and correct cracked, corroded, or fractured carriage spindles, and to prevent severe flap asymmetry, which could result in reduced control or loss of controllability of the airplane.

**DATES :**  We must receive comments on this proposed AD by April 15, 2010.

Discussion

On November 24, 2003, we issued AD 2003–24–08, Amendment 39–13377 (68 FR 67027, December 1, 2003), for all Model 737–100, –200, –200C, –300, –400, and –500 series airplanes. That


### 9138 Federal Register / Vol. 75, No. 39 / Monday, March 1, 2010 / Proposed Rules

AD currently requires repetitive inspections to find cracks, fractures, or corrosion of each carriage spindle of the left and right outboard mid-flaps, and corrective action if necessary. That AD also currently requires repetitive gap checks of the inboard and outboard carriage of the outboard mid-flaps to detect fractured carriage spindles, and corrective actions if necessary. That AD resulted from a report indicating that the inboard and outboard carriage spindles (number 7 and 8 carriage spindles) were fractured on the right outboard flap during approach to landing. We issued that AD to detect and correct cracked, corroded, or fractured carriage spindles, and to prevent severe flap asymmetry, which could result in reduced control or loss of controllability of the airplane. Actions Since Existing AD Was Issued

The preamble to AD 2003–24–08 explains that we considered the requirements ‘‘ interim action’’ and were considering further rulemaking. We now have determined that further rulemaking is indeed necessary, and this proposed AD follows from that determination.

Relevant Service Information

We have reviewed Boeing Alert Service Bulletin 737–57A1218, Revision 5, dated February 9, 2009. The service bulletin describes procedures for repetitive detailed and magnetic particle inspections to detect discrepancies (including corrosion, pitting, and cracks) of the carriage spindle, repetitive measurements to determine the diameter of certain areas of the carriage spindle, and applicable corrective actions. The corrective actions include repairing any corrosion or pitting, or replacement with a new or serviceable carriage. The service bulletin also describes procedures for repetitive overhauls of the carriage. In addition, the service bulletin describes procedures for repetitive replacements of any carriage when it has reached its maximum life limit.
FAA’s Determination and Requirements of the Proposed AD

We have evaluated all pertinent information and identified an unsafe condition that is likely to develop on other airplanes of the same type design. For this reason, we are proposing this AD, which would supersede AD 2003– 24–08 and would retain certain requirements of the existing AD. This proposed AD would require any new or serviceable carriage spindle installed per the requirements of the existing AD to meet minimum allowable diameter measurements taken at three locations of the spindle. This proposed AD also would require accomplishing the actions specified in the service bulletin described previously. Change to Existing AD

This proposed AD would retain certain requirements of AD 2003–24–08. Since AD 2003–24–08 was issued, the AD format has been revised, and certain paragraphs have been rearranged. As a result, the corresponding paragraph identifiers have changed in this proposed AD, as listed in the following table:

Costs of Compliance

There are about 2,852 airplanes of the affected design in the worldwide fleet. The following table provides the estimated costs for U.S. operators to comply with this proposed AD.

1 $7,000 per spindle; 4 spindles per airplane.

2 $15,000 per spindle; 4 spindles per airplane.

The cost impact figures discussed above are based on assumptions that no operator has yet accomplished any of the actions required by this AD, and that no operator would accomplish those actions in the future if this AD were not adopted. However, we have been advised that the carriages are already being overhauled and replaced on some affected airplanes. In addition, the replacement cycle is approximately every 20 years. Therefore, the future economic cost impact of this proposed rule on U.S. operators is expected to be less than the cost impact figures indicated above.
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 have 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 that the 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); 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 proposed AD and placed it in the AD docket. See the **ADDRESSES** section for a location to examine the regulatory evaluation. List of Subjects in 14 CFR Part 39

Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. The Proposed Amendment
