On paragraph (f) (2) (i) the AD state ".... and Section 9 of P&WC Special Instruction (SI) P&WC 22-2012R2, dated April 4, 2012".
Please add a note stating that the operators that performed the Ultrasonic inspection as per SI P&WC 22-2012R1, dated March 23rd, 2012 are considered compliant.
The justification for this is: the revision R2 is adding pictures for clarity and adding one acceptable case type in regards with the ultrasonic inspection findings.
Therefore the R1 is more stringent than R2, both are considered compliant.
This revision can be made available if required.
Best regards,
