AD 2012-02-10 Airworthiness Directives; CPAC, Inc. Airplanes
Makes named: commander. Models named: 112, 112B, 112TC, 112TCA, 114, 114A, 114B, 114TC. Read the applicability below — it usually turns on serial or part numbers too.
Applicability*9
This AD applies to CPAC, Inc. (type certificate formerly held by Commander Aircraft Corporation, Gulfstream Aerospace Corporation, and Rockwell International) Models 112, 112B, 112TC, 112TCA, 114, 114A, 114B, and 114TC airplanes, all serial numbers, certificated in any category. Type Certificate No. A12SO does not include Models 112A and 115. The Model 112A is a Rockwell “marketing name” for the Model 112. The Model 115 is a Rockwell “marketing name” for the Model 114. Since they are type-certificated as Model 112 and Model 114, this AD is applicable to the Models 112A and 115.
Compliance
Comply with this AD within the compliance times specified, unless already done. The inspection intervals and procedures in this AD take precedence over those contained in Parts Manufacturer Approval (PMA) Elevator Spars 44211-RE9 and 44211-RE10, Instructions for Continued Airworthiness, original issue date May 5, 2011.
Required actions
Within the next 5 hours time-in-service (TIS) after April 4, 2011 (the effective date retained from AD 2011-07-13 (76 FR 18376, April 4, 2011)), visually inspect the left-hand (LH) and right-hand (RH) elevator spar behind and around the outboard hinge bracket on the elevator spar for cracks. Do the inspection following the procedures specified in paragraph (j) of this AD. If cracks are found during this inspection, take the necessary corrective actions specified in paragraph (k) of this AD.
Unsafe condition
This AD was prompted by reports of a total of nine elevator spar cracks across seven of the affected airplanes, including a crack of 2.35 inches just below the outboard hinge of the right-hand elevator. We are issuing this AD to prevent structural failure of the elevator spar due to such cracking, which could result in separation of the elevator from the airplane with consequent loss of control.
Affected ADs
This AD supersedes AD 2011-07-13, Amendment 39-16650 (76 FR 18376, April 4, 2011).
