AD 2006-21-11 Airworthiness Directives; Turbomeca Turmo IV A and IV C Series Turboshaft Engines
Applicability*9
This AD applies to Turbomeca Turmo IV A and IV C series turboshaft engines with flexible lubrication pipes, part number (P/N) 0 249 92 813 0 or P/N 0 249 92 916 0, installed. These engines are installed on but not limited to, Aerospatiale SA 330—PUMA helicopters.
Compliance
You are responsible for having the actions required by this AD performed within the compliance times specified unless the actions have already been done. Initial Actions (f) Before further flight: (1) Identify the curing batch of the flexible lubrication pipes. (2) If the two engines installed on the same helicopter have pipes with a curing batch of “2T03” (meaning 2nd quarter of 2003) or subsequent batch, replace one of the pipes with a pipe having a curing batch before batch “2T03”. (3) On the other engine, or on a helicopter that has only one engine affected by this AD, borescope-inspect the pipe for deterioration, visually inspect for oil leakage, and visually inspect the oil filter for black particle deterioration from the pipe. Replace the pipe if deterioration or leakage is found, with a pipe having a curing batch before batch “2T03”. Repetitive Actions (g) Within every additional 25 operating hours, on engines still having an affected flexible lubrication pipe, borescope-inspect the pipe for deterioration, visually inspect pipe for oil leakage, and visually inspect the oil filter for black particle deterioration from the pipe. Replace the pipe if deterioration or leakage is found, with a pipe having a curing batch before batch “2T03”. (h) Information on performing the initial and repetitive actions in this AD can be found in Turbomeca Alert Mandatory Service Bulletin No. A249 72 0802, Update No. 1, dated August 3, 2006. Alternative Methods of
Unsafe condition
This AD results from 7 reports of oil leakage due to the deterioration of certain flexible lubrication pipes, part number (P/N) 0 249 92 813 0. We are issuing this AD to prevent dual-engine failure on a twin-engine helicopter.

You just looked this one up by hand
TrackAD holds all 12,278 of them and matches them against the aircraft you actually look after — airframe, engine, propeller and appliances in one pass — then works out what falls due and when.
- Bring your existing list in from a spreadsheet Paste the rows straight out of Excel. Headers like C/W Date and N/A are read for you.
- A copy that works when this does not One file. No internet, no login, no this software running. For the morning something has to be produced and the computer is not cooperating.
- $5 a month, or $50 a year Up to 50 aircraft on either.
