EA-300S 001 through 028 EA-300L 001 through 015 Note 1: This AD applies to each airplane identified in the preceding applicability provision, regardless of whether it has been modified, altered, or repaired in the area subject to the requirements of this AD. For airplanes that have been modified, altered, or repaired so that the performance of the requirements of this AD is affected, the owner/operator must request approval for an alternative method of compliance in accordance with paragraph (f) of this AD. The request should include an assessment of the effect of the modification, alteration, or repair on the unsafe condition addressed by this AD; and, if the unsafe condition has not been eliminated, the request should include specific proposed actions to address it.

Required as follows: 1. Inspections specified in this AD are required within the next 50 hours time-in-service (TIS) after the effective date of this AD, unless already accomplished, and thereafter at intervals not to exceed 50 hours TIS. 2. Replacements or other follow-on corrective actions specified in this AD are required prior to further flight after the inspection when the discrepancy was found. To prevent failure of the rudder pedal footrest caused by overloading the rudder pedal safety control stop, which could result in loss of directional control of the airplane, accomplish the following: (a) Inspect the rudder pedal alignment in accordance with Figure 1 and Figure 2 and the Instructions Part I.1 section of EXTRA Service Bulletin No. 300-3-95, Issue: B, dated May 12, 1998. If not aligned, prior to further flight, accomplish one of the following, as applicable, in accordance with the service bulletin: (1) Re-rig the rudder cables to attain proper alignment; or (2) Replace the rudder cables if alignment cannot be attained. (b) For all airplanes equipped at manufacture with a safety control stop (See Note 2 of this AD), inspect the safety control stop for wear (rubbing, scrapes, etc.) in accordance with the Instructions Part I.2 section of EXTRA Service Bulletin No. 300-3- 95, Issue: B, dated May 12, 1998. If the safety control stop is worn, prior to further flight, replace the safety control stop and accomplish one of the following, as applicable, in accordance with the service bulletin: (1) Re-rig the rudder cable if elongation of the cable is not evident; or (2) Replace the rudder cable if elongation of the cable is evident.

(d) For all airplanes equipped at manufacture with a safety control stop (See Note 2 of this AD), inspect the safety control stop clearance in accordance with the Instructions Part I.4 and Instructions Part II section of EXTRA Service Bulletin No. 300-3-95, Issue: B, dated May 12, 1998. If the clearance does not meet the minimum specified clearance, prior to further flight, accomplish one of the following, as applicable, in accordance with the service bulletin: (1) Adjust the foot rest to meet the required clearance if elongation of the cable is not evident; or (2) Replace the rudder cable if elongation of the cable is evident.
