020310 dated 3 June 2002 or later approved revisions. 

2. For group 1 aircraft: 

Oil lines with P/N 41-23-56-000, 53-11-10-000, 53-20-13-000, 53-20-14-000 or 53-34-10-010

(Apex Aircraft SB No. 020310 and Alpha Aviation SB No. AA-SB-79-001 refer) 

Compliance: 1. Within six months after 29 June 2006 (the effective date of DCA/R2000/34), unless 

previously accomplished. 

2. From 29 June 2006 (the effective date of DCA/R2000/34). 

3. Within the next 50 hours TIS or by 30 April2012 whichever occurs sooner. 

4. From 23 February 2012. 

Effective Date: 23 February 2012 

Background: It has been determined that the oil lines fitted to affected aircraft are not fire resistant and not 

compliant with the requirements in FAR 23.1183. To correct this unsafe condition the Civil 

Aviation Authority of New Zealand issued DCA/R2000/34 requiring the replacement of oil lines 

with fire resistant lines. Since the issue of that AD it has been determined that the oil 

transmitter hoses are also not compliant with FAR 23.1183. DCA/R2000/40 retains the 

requirements in superseded DCA/R2000/34. The AD requirement expanded to include the 

replacement of the oil pressure transducer hoses.
