Superseded. A later AD replaced this one: AD 2000-11-16, AD 2006-07-15, AD 2009-26-11. Comply with the one in force.
Airplanes with the following model and serial number designations with or without a -DC suffix, certificated in any category: Group 1 Airplanes Model Serial Nos. S-2R................................... 5000R through 5099R. S2R-R1340.............................. R1340-011, R1340-012, R1340-019, R1340-020, R1340-024, R1340-025, and R1340-027. S2R-R1820.............................. R1820-001 through 1820-035. S2R-T34................................ 6000R through 6049R, T34-001 through T34-143, T34-145, T34-147 through T34-167, T34-171, T34-180, and T34-181.\1\ S2R-T15................................

G1-101 through G1-108. \1\ The serial numbers of the Model S2R-T34 airplanes could incorporate T34-xxx, T36-xxx, T41-xxx, or T42-xxx. This AD applies to all of these serial number designations as they are all Model S2R-T34 airplanes. \2\ The serial numbers of the Model S2R-T15 airplanes could incorporate T15-xx and T27-xx. This AD applies to both of these serial number designations as they are both Model S2R-T15 airplanes. Group 2 Airplanes Model Serial Nos. S2R-R1340.............................. R1340-028 through R1340-035. S2R-R1820.............................. R1820-036. S2R-T65................................ T65-001 through T65-017. S2RHG-T65.............................. T65-002 through T65-017. S2R-T34................................ T34-144, T34-146, T34-168, T34-169, T34-172 through T34-179, and T34- 189 through T34-226.\1\ S2R-T45................................ T45-001 through T45-014. S2R-G6................................. G6-101 through G6-146. S2R-G10................................ G10-101 through G10-138. S2R-G5................................. G5-101 through G5-105. \1\ The serial numbers of the Model S2R-T34 airplanes could incorporate T34-xxx, T36-xxx, T41-xxx, or T42-xxx. This AD applies to all of these serial number designations as they are all Model S2R-T34 airplanes. Group 3 Airplanes \1\ Model Serial Nos. 600 S2D................................ All serial numbers beginning with 600-1311D. S-2R................................... 1380R and 1416R through 4999R. S2R-R1340.............................. R1340-001 through R1340-010, R1340-013 through R1340-018, R1340-021 through R1340-023, and R1340-026. S2R-R3S................................ R3S-001 through R3S-011. \1\ Any Group 3 airplane that has been modified with a hopper of a capacity over 400 gallons, a piston engine greater than 600 horsepower, or any gas turbine engine makes the airplane a Group 1 airplane for the purposes of this AD. The owner/operator must inspect the airplane at the Group 1 compliance time specified in the Compliance section of this AD.
This amendment supersedes Airworthiness Directive (AD) 97-13- 11, which currently requires inspecting the \1/4\-inch and \5/16\-inch bolt hole areas on the lower spar caps for fatigue cracking on Ayres S2R series airplanes, and replacing any lower spar cap if fatigue cracking is found. That AD resulted from an accident on an Ayres S2R series airplane where the wing separated from the airplane in flight. AD 97-13-11 incorrectly references the Ayres Model S2R-R1340 airplanes as Model S2R-1340R. This AD requires the same actions as AD 97-13-11, but corrects the designation of the Model S2R-R1340 airplanes. The actions specified by this AD are intended to detect fatigue cracking of the lower spar caps, which, if not corrected, could result in the wing separating from the airplane with consequent loss of control of the airplane.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
