ACTION: Notice of proposed rulemaking (NPRM). AGENCY: SUMMARY: The FAA proposes to supersede an existing airworthiness directive (AD) that applies to certain McDonnell Douglas airplanes, as listed above. The existing AD currently requires an initial general visual or dye penetrant inspection, repetitive dye penetrant inspections, and replacement, as necessary, of the rudder pedal bracket. This proposed AD would also require, for certain airplanes, replacing the rudder pedal bracket assemblies with new, improved parts, which would terminate the repetitive inspections. This proposed AD is prompted by a report of numerous cracked rudder pedal brackets found during inspections of certain affected airplanes. We are proposing this AD to prevent failure of the rudder pedal bracket assembly, which could result in the loss of rudder and braking control at either the captain’s or first officer’s position. DATES: We must receive comments on this proposed AD by May 20, 2005.

Discussion On June 9, 1989, we issued AD 89– 14–02, amendment 39–6245 (54 FR 27156, June 28, 1989), for certain McDonnell Douglas Model DC–8, DC–9 and C–9 (Military) series airplanes, including Model DC–9–80 series airplanes and Model MD–88 airplanes. That AD requires an initial general visual or dye penetrant inspection, repetitive dye penetrant inspections, and replacement, as necessary, of the rudder pedal bracket. That AD was prompted by several reports of fatigue failures in the captain’s rudder pedal bracket assembly on Model DC–9 series airplanes. We issued that AD to prevent failure of the rudder pedal bracket assembly, which could result in the loss of rudder and braking control at either the captain’s or first officer’s position. Actions Since Existing AD Was Issued The Air Transport Association (ATA) of America and the Aerospace Industries Association (AIA) of America agreed to undertake the task of identifying and implementing procedures to ensure the continued structural airworthiness of aging transport category airplanes. An Airworthiness Assurance Working Group (AAWG) was established in August 1988, with members representing aircraft manufacturers, operators, regulatory authorities, and other aviation industry representatives worldwide. The objective of the AAWG was to sponsor ‘‘Steering Task Groups (STG)’’ to: 1. Select service bulletins, applicable to each airplane model in the transport fleet, to be recommended for mandatory modification of aging airplanes; 2. Develop corrosion-directed inspections and prevention programs; 3. Review the adequacy of each operator’s structural maintenance program; 4. Review and update the Supplemental Inspection Documents (SID); and 5. Assess repair quality. E:\FR\FM\05APP1.SGM 05APP1 17217 Federal Register / Vol. 70, No. 64 / Tuesday, April 5, 2005 / Proposed Rules Based on the results of this review, the DC–9 STG for Model DC–9–10, –20, –30, –40, and –50 series airplanes; Model DC–9–81 (MD–81), DC–9–82 (MD–82), DC–9–83 (MD–83), and DC–9– 87 (MD–87) airplanes; and Model MD– 88 airplanes; has determined that for these airplanes, further corrective action is necessary to prevent failure of the rudder pedal bracket assembly, which could result in the loss of rudder and braking control at either the captain’s or first officer’s positions. In addition, we have received a report of numerous cracked rudder pedal brackets found during inspections of Model DC–9–10, –20, –30, –40, and –50 series airplanes; Model DC–9–81 (MD– 81), DC–9–82 (MD–82), DC–9–83 (MD– 83), and DC–9–87 (MD–87) airplanes; and Model MD–88 airplanes. AD 89–14–02 does not provide a terminating action for these certain airplanes and instead requires repetitive inspections after the replacement of the rudder pedal bracket assemblies. Since operators could fly these airplanes another 40,000 landings after the replacement of the rudder pedal bracket assemblies, new, improved parts made of aluminum casting were developed to address the unsafe condition of AD 89– 14–02. We have determined we can better ensure long-term continued operational safety by modifications or design changes to remove the source of the problem, rather than by repetitive inspections. Therefore, for certain airplanes, the proposed AD would require replacement of the rudder pedal bracket assemblies with new, improved parts made of aluminum casting, which would terminate the repetitive inspections. The proposed AD would require that the replacement with new, improved parts be accomplished before the accumulation of 75,000 total landings on a rudder pedal bracket assembly, or within 60 months after the effective date of this AD, whichever occurs later. We have also determined that the other affected Model DC–8–11, DC–8– 12, DC–8–21, DC–8–31, DC–8–32, DC– 8–33, DC–8–41, DC–8–42, and DC–8–43 airplanes; Model DC–8F–54 and DC– 8F–55 airplanes; and Model DC–8–50, –60, –60F, –70, and –70F series airplanes in AD 89–14–02 do not VerDate jul<14>2003 15:05 Apr 04, 2005 Jkt 205001 require replacement of rudder pedal bracket assemblies with new, improved parts made of aluminum casting. Replacement with a new part having the same part number, if cracks are detected, is sufficient in addressing the unsafe condition of this proposed AD, since these airplanes are not expected to fly another 40,000 landings after the replacement. accomplishing the terminating action (replacement is on-condition). This proposed AD, however, would require operators to accomplish, for certain airplanes, the terminating action before the accumulation of 75,000 total landings on a rudder pedal bracket assembly, or within 60 months after the effective date of this AD, whichever occurs later. Relevant Service Information We have reviewed McDonnell Douglas Alert Service Bulletin A27–307, Revision 6, dated December 19, 1994. The service bulletin describes procedures for replacing the captain’s and first officer’s rudder pedal bracket assemblies with parts having the same part number; or replacing with new, improved parts, which ends the repetitive inspections for McDonnell Douglas Model DC–9–10, –20, –30, –40, and –50 series airplanes; Model DC–9– 81 (MD–81), DC–9–82 (MD–82), DC–9– 83 (MD–83), DC–9–87 (MD–87) airplanes; and Model MD–88 airplanes. Accomplishing the actions specified in the service information is intended to adequately address the unsafe condition. Changes to Existing AD FAA’s Determination and Requirements of the Proposed AD The unsafe condition described previously is likely to exist or develop on other airplanes of the same type design that may be registered in the U.S. at some time in the future. We are proposing to supersede AD 89–14–02. This proposed AD would retain the requirements of the existing AD. This proposed AD would also require, for certain airplanes, accomplishing the actions specified in the service bulletin described previously, except as discussed under ‘‘Differences Between the Proposed AD and Service Bulletin.’’ Differences Between Proposed Rule and Service Bulletin This proposed AD would require replacement of the rudder pedal bracket assemblies with new, improved parts, which would terminate the repetitive inspections. The service bulletin provides the termination action as an option. The service bulletin does not recommend a compliance time for PO 00000 Frm 00006 Fmt 4702 Sfmt 4702 This proposed AD would retain all requirements of AD 89–14–02. Since AD 89–14–02 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: REVISED PARAGRAPH IDENTIFIERS Requirement in AD 89–14–02 paragraph A .............. paragraph B .............. Corresponding requirement in this proposed AD paragraph (f). paragraph (g). We have also changed all references to any ‘‘visual inspection’’ in AD 89– 14–02 to ‘‘general visual inspection’’ in this proposed AD and added a note to clarify the definition of a general visual inspection. In this proposed AD, we have also revised the applicability of AD 89–14– 02 to identify model designations as published in the most recent type certificate data sheet for the affected models. We have clarified the compliance time in paragraphs (f) and (g) of this AD to specify 40,000 total landings. Costs of Compliance There are about 2,025 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. The new replacements of this proposed AD are applicable only to Model DC–9–10, –20, –30, –40, and –50 series airplanes; Model DC–9–81 (MD–81), DC–9–82 (MD–82), DC–9–83 (MD–83), and DC–9– 87 (MD–87) airplanes; and Model MD– 88 airplanes.

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. See the ADDRESSES section for a location to examine the regulatory evaluation.

ACTION: Notice of proposed rulemaking (NPRM).

-----------------------------------------------------------------------

SUMMARY: The FAA proposes to supersede an existing airworthiness 
directive (AD) that applies to certain McDonnell Douglas airplanes, as 
listed above. The existing AD currently requires an initial general 
visual or dye penetrant inspection, repetitive dye penetrant 
inspections, and replacement, as necessary, of the rudder pedal 
bracket. This proposed AD would also require, for certain airplanes, 
replacing the rudder pedal bracket assemblies with new, improved parts, 
which would terminate the repetitive inspections. This proposed AD is 
prompted by a report of numerous cracked rudder pedal brackets found 
during inspections of certain affected airplanes. We are proposing this 
AD to prevent failure of the rudder pedal bracket assembly, which could 
result in the loss of rudder and braking control at either the 
captain's or first officer's position.

DATES: We must receive comments on this proposed AD by May 20, 2005.

Discussion

    On June 9, 1989, we issued AD 89-14-02, amendment 39-6245 (54 FR 
27156, June 28, 1989), for certain McDonnell Douglas Model DC-8, DC-9 
and C-9 (Military) series airplanes, including Model DC-9-80 series 
airplanes and Model MD-88 airplanes. That AD requires an initial 
general visual or dye penetrant inspection, repetitive dye penetrant 
inspections, and replacement, as necessary, of the rudder pedal 
bracket. That AD was prompted by several reports of fatigue failures in 
the captain's rudder pedal bracket assembly on Model DC-9 series 
airplanes. We issued that AD to prevent failure of the rudder pedal 
bracket assembly, which could result in the loss of rudder and braking 
control at either the captain's or first officer's position.

Actions Since Existing AD Was Issued

    The Air Transport Association (ATA) of America and the Aerospace 
Industries Association (AIA) of America agreed to undertake the task of 
identifying and implementing procedures to ensure the continued 
structural airworthiness of aging transport category airplanes. An 
Airworthiness Assurance Working Group (AAWG) was established in August 
1988, with members representing aircraft manufacturers, operators, 
regulatory authorities, and other aviation industry representatives 
worldwide. The objective of the AAWG was to sponsor ``Steering Task 
Groups (STG)'' to:
    1. Select service bulletins, applicable to each airplane model in 
the transport fleet, to be recommended for mandatory modification of 
aging airplanes;
    2. Develop corrosion-directed inspections and prevention programs;
    3. Review the adequacy of each operator's structural maintenance 
program;
    4. Review and update the Supplemental Inspection Documents (SID); 
and
    5. Assess repair quality.

[[Page 17217]]

    Based on the results of this review, the DC-9 STG for Model DC-9-
10, -20, -30, -40, and -50 series airplanes; Model DC-9-81 (MD-81), DC-
9-82 (MD-82), DC-9-83 (MD-83), and DC-9-87 (MD-87) airplanes; and Model 
MD-88 airplanes; has determined that for these airplanes, further 
corrective action is necessary to prevent failure of the rudder pedal 
bracket assembly, which could result in the loss of rudder and braking 
control at either the captain's or first officer's positions.
    In addition, we have received a report of numerous cracked rudder 
pedal brackets found during inspections of Model DC-9-10, -20, -30, -
40, and -50 series airplanes; Model DC-9-81 (MD-81), DC-9-82 (MD-82), 
DC-9-83 (MD-83), and DC-9-87 (MD-87) airplanes; and Model MD-88 
airplanes.
    AD 89-14-02 does not provide a terminating action for these certain 
airplanes and instead requires repetitive inspections after the 
replacement of the rudder pedal bracket assemblies. Since operators 
could fly these airplanes another 40,000 landings after the replacement 
of the rudder pedal bracket assemblies, new, improved parts made of 
aluminum casting were developed to address the unsafe condition of AD 
89-14-02.
    We have determined we can better ensure long-term continued 
operational safety by modifications or design changes to remove the 
source of the problem, rather than by repetitive inspections. 
Therefore, for certain airplanes, the proposed AD would require 
replacement of the rudder pedal bracket assemblies with new, improved 
parts made of aluminum casting, which would terminate the repetitive 
inspections. The proposed AD would require that the replacement with 
new, improved parts be accomplished before the accumulation of 75,000 
total landings on a rudder pedal bracket assembly, or within 60 months 
after the effective date of this AD, whichever occurs later.
    We have also determined that the other affected Model DC-8-11, DC-
8-12, DC-8-21, DC-8-31, DC-8-32, DC-8-33, DC-8-41, DC-8-42, and DC-8-43 
airplanes; Model DC-8F-54 and DC-8F-55 airplanes; and Model DC-8-50, -
60, -60F, -70, and -70F series airplanes in AD 89-14-02 do not require 
replacement of rudder pedal bracket assemblies with new, improved parts 
made of aluminum casting. Replacement with a new part having the same 
part number, if cracks are detected, is sufficient in addressing the 
unsafe condition of this proposed AD, since these airplanes are not 
expected to fly another 40,000 landings after the replacement.

Relevant Service Information

    We have reviewed McDonnell Douglas Alert Service Bulletin A27-307,
    Revision 6, dated December 19, 1994. The service bulletin describes 
procedures for replacing the captain's and first officer's rudder pedal 
bracket assemblies with parts having the same part number; or replacing 
with new, improved parts, which ends the repetitive inspections for 
McDonnell Douglas Model DC-9-10, -20, -30, -40, and -50 series 
airplanes; Model DC-9-81 (MD-81), DC-9-82 (MD-82), DC-9-83 (MD-83), DC-
9-87 (MD-87) airplanes; and Model MD-88 airplanes. Accomplishing the 
actions specified in the service information is intended to adequately 
address the unsafe condition.

FAA's Determination and Requirements of the Proposed AD

    The unsafe condition described previously is likely to exist or 
develop on other airplanes of the same type design that may be 
registered in the U.S. at some time in the future. We are proposing to 
supersede AD 89-14-02. This proposed AD would retain the requirements 
of the existing AD. This proposed AD would also require, for certain 
airplanes, accomplishing the actions specified in the service bulletin 
described previously, except as discussed under ``Differences Between 
the Proposed AD and Service Bulletin.''

Differences Between Proposed Rule and Service Bulletin

    This proposed AD would require replacement of the rudder pedal 
bracket assemblies with new, improved parts, which would terminate the 
repetitive inspections. The service bulletin provides the termination 
action as an option.
    The service bulletin does not recommend a compliance time for 
accomplishing the terminating action (replacement is on-condition). 
This proposed AD, however, would require operators to accomplish, for 
certain airplanes, the terminating action before the accumulation of 
75,000 total landings on a rudder pedal bracket assembly, or within 60 
months after the effective date of this AD, whichever occurs later.

Changes to Existing AD

    This proposed AD would retain all requirements of AD 89-14-02. 
Since AD 89-14-02 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:

                      Revised Paragraph Identifiers
------------------------------------------------------------------------
                                             Corresponding  requirement

------------------------------------------------------------------------
paragraph A...............................  paragraph (f).
paragraph B...............................  paragraph (g).
------------------------------------------------------------------------

    We have also changed all references to any ``visual inspection'' in 
AD 89-14-02 to ``general visual inspection'' in this proposed AD and 
added a note to clarify the definition of a general visual inspection.
    In this proposed AD, we have also revised the applicability of AD 
89-14-02 to identify model designations as published in the most recent 
type certificate data sheet for the affected models.
    We have clarified the compliance time in paragraphs (f) and (g) of 
this AD to specify 40,000 total landings.

Costs of Compliance

    There are about 2,025 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. The new replacements of 
this proposed AD are applicable only to Model DC-9-10, -20, -30, -40, 
and -50 series airplanes; Model DC-9-81 (MD-81), DC-9-82 (MD-82), DC-9-
83 (MD-83), and DC-9-87 (MD-87) airplanes; and Model MD-88 airplanes.

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. See the ADDRESSES section for a location 
to examine the regulatory evaluation.

Unsafe Condition

    (d) This AD was prompted by a report of numerous cracked rudder 
pedal brackets found during inspections of certain affected 
airplanes. We are issuing this AD to prevent failure of the rudder 
pedal bracket assembly, which could result in the loss of rudder and 
braking control at either the captain's or first officer's position.

Compliance

    (e) You are responsible for having the actions required by this 
AD performed within the compliance times specified, unless the 
actions have already been done.

Requirements of AD 89-14-02

    (f) Prior to the accumulation of 40,000 total landings or within 
30 days after July 5, 1989 (the effective date of AD 89-14-02), 
whichever occurs later, perform either a general visual inspection 
or dye penetrant inspection for cracks of the captain's and first 
officer's rudder pedal bracket, part numbers (P/N) 5616067 and 
5616068, respectively, in accordance with McDonnell Douglas Alert 
Service Bulletins A27-273 (for Model DC-8-11, DC-8-12, DC-8-21, DC-
8-31, DC-8-32, DC-8-33, DC-8-41, DC-8-42, and DC-8-43 airplanes; 
Model DC-8F-54 and DC-8F-55 airplanes; and Model DC-8-50, -60, -60F, 
-70, and -70F series airplanes) or A27-307 (for Model DC-9-10, -20, 
-30, -40, and -50 series airplanes; Model DC-9-81 (MD-81), DC-9-82 
(MD-82), DC-9-83 (MD-83), and DC-9-87 (MD-87) airplanes; and Model 
MD-88 airplanes), as applicable, both dated May 16, 1989.

    Note 1: For the purposes of this AD, a general visual inspection 
is: ``A visual examination of an interior or exterior area, 
installation, or assembly to detect obvious damage, failure, or 
irregularity. This level of inspection is made from within touching 
distance unless otherwise specified. A mirror may be necessary to 
ensure visual access to all surfaces in the inspection area. This 
level of inspection is made under normally available lighting 
conditions such as daylight, hangar lighting, flashlight, or 
droplight and may require removal or opening of access panels or 
doors. Stands, ladders, or platforms may be required to gain 
proximity to the area being checked.''



    Note 2: McDonnell Douglas Alert Service Bulletins A27-273 and 
A27-307, both dated May 16, 1989, are hereinafter referred to as ASB 
A27-273 and ASB A27-307, respectively.

    (1) If an initial general visual inspection is accomplished, and 
no cracks are found, perform a dye penetrant inspection of the 
rudder pedal bracket assembly within 180 days after the general 
visual inspection, and thereafter accomplish dye penetrant 
inspections at intervals not to exceed 12 months or 2,500 landings, 
whichever occurs earlier.
    (2) If an initial dye penetrant inspection is accomplished, and 
no cracks are found, accomplish repetitive dye penetrant inspections 
at intervals not to exceed 12 months or 2,500 landings, whichever 
occurs earlier.
    (g) If cracks are detected, prior to further flight, remove and 
replace the rudder pedal bracket assembly in accordance with ASB 
A27-273 or A27-307, as applicable. Prior to the accumulation of 
40,000 total landings after replacement with the new part, resume 
the repetitive inspections in accordance with paragraph (f) in this 
AD.
