Airworthiness Directive · Amendment 39-16498 · Austro Engine GmbH Model E4 Diesel Piston Engines
Austro Engine GmbH Model E4 Diesel Piston Engines
Superseded. A later AD replaced this one: AD 2011-18-19. Comply with the one in force.
This AD applies to Austro Engine GmbH model E4 diesel piston engines. These engines are installed on, but not limited to, Diamond Aircraft Industries DA 40 NG and DA 42 NG airplanes.
We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) issued by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:
Unless already done, do the following actions.
(1) Inspect the fuel pressure supply for excessive oscillations using the inspection schedule in Table 1 of this AD.
| Accumulated time-since-new: | Compliance time: |
|---|---|
| 45 flight hours or more, on the effective date of this AD. | Within 10 flight hours after the effective date of this AD. |
| Fewer than 45 flight hours, on the effective date of this AD. | At the next scheduled 50 flight hour inspection. |
| Repetitive inspections. | At each 50 flight-hour scheduled inspection. |
(2) Replace the high-pressure fuel pump before further flight with a serviceable high-pressure fuel pump if the oscillations exceed 300mV (750hPa).
(3) Use Austro Engine GmbH Work Instruction No. WI-MSB-E4-009, dated October 7, 2010, to do the inspections.
None.
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.
