Airworthiness Directive · Amendment 39-14105 · McDonnell Douglas Model 717-200 Airplanes
McDonnell Douglas Model 717-200 Airplanes
This AD applies to McDonnell Douglas Model 717-200 airplanes, fuselage numbers 5002 through 5134 inclusive; certificated in any category.
The FAA is adopting a new airworthiness directive (AD) for certain McDonnell Douglas Model 717-200 airplanes. This AD requires replacing eight brake fuses of the hydraulic quantity limiter with new or modified and reidentified fuses. This AD is prompted by reports indicating that brake fuses of the hydraulic quantity limiter of the main landing gear have failed. We are issuing this AD to prevent loss of both hydraulic and brake systems if one fuse on each hydraulic system were to fail simultaneously, and consequent reduced controllability of the airplane.
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
At the applicable time in Table 1 of this AD, do the action required by paragraph (g) of this AD.
| For airplanes having— | Compliance time |
|---|---|
| (1) Less than 5,000 total flight cycles as of the effective date of this AD | Within 3,600 flight cycles after the effective date of this AD. |
| (2) 5,000 or more total flight cycles as of the effective date of this AD | Within 1,500 flight cycles after the effective date of this AD. |
Replace the eight brake fuses of the hydraulic quantity limiter by doing either Option 1 or Option 2 in Table 2 of this AD in accordance with Boeing Alert Service Bulletin 717-32A0031, dated September 10, 2004.
| Option— | Replace eight fuses having part number (P/N) 7918282-5503 with— |
|---|---|
| 1 | New fuses having P/N 7918282-5505. |
| 2 | Modified and reidentified fuses having P/N 7918282-5505. |
Note 1: Boeing Alert Service Bulletin 717-32A0031 refers to Parker Hannifin Corporation Stratoflex Products Division Service Bulletin 836SD-8-6-20, Revision 1, dated June 23, 2004, as an additional source of service information for modifying and reidentifying the brake fuses.
As of the effective date of this AD, no person may install a brake fuse, P/N 7918282-5503, on any airplane.
