1. INFORMATION

NOTE: Reissues or revisions are automatically provided to the subscription holder of this manual. Additional publications are listed on the web at http://pubs.hawkerbeechcraft.com. For Information on these publications or to check subscription status, contact the Technical Manual Distribution Center (TMDC) at 1-800-796-2665 or (316) 676-8238, fax (316) 671-2540, E-mail [email protected].

The Interactive Maintenance Library (IML) contains selectedManuals in a digital format. This manual is available as a single CDand is not included in IML.

A. General

This manual was prepared by Hawker Beechcraft Corporationto provide operators with Maintenance and OperationalProcedures to use in association with the FAA Master MinimumEquipment List (MMEL). The operator should place theappropriate Preamble from the FAA MMEL ahead of thissection, in the written Minimum Equipment List (MEL) for thatoperator.

Numerous procedures were copied from the existing AircraftMaintenance Manual (AMM) to develop this M&O so operatorswould have necessary requirements for their MEL under 14CFR 91.213. Many of these procedures were reviewed with theFAA-AEG to address specific issues when Revision 6 of theMMEL was developed. The operator should be familiar withFAA AC91-67 and be aware that the operator is responsible forprocedures used in the individual MEL.

All items in the current FAA MMEL are listed. The operator maytailor entries that are not directly applicable before obtainingauthorization from the FAA for an airplane-specific MEL.

Maintenance procedures may require the use of the applicableAMM and/or the Illustrated Parts Catalog (IPC) to aid inidentification of location or supplement procedures provided.

Maintenance procedures are for certified mechanics. Someprocedures can be performed by an “appropriately trained crewmember” when approved by the regulatory authority.

Operational procedures are to be performed by either or bothflight crew members.

Individual procedures may include application of appropriateplacards. This document installs placards where it is essentialto provide flight crew awareness of inoperative equipment.

The M&O for Minimum Equipment List is prepared inaccordance with the requirements of Air Transport Association(ATA) Specification 2200 with respect to the arrangement andcontent of the System/Chapters within the designatednumbering system.

It shall be the responsibility of the owner/operator to make surethat the latest revision of the publications referenced in thismanual are utilized during operation, servicing andmaintenance of the airplane.

Hawker Beechcraft Corporation expressly reserves the right tosupersede, cancel and/or declare obsolete any parts, partnumbers, kits or publications that may be referenced in thismanual without prior notice.

WARNING: Use only parts obtained from sources approved by Hawker Beechcraft Corporation, in connection with the maintenance and repair of Hawker Beechcraft Corporation airplanes.

Genuine Hawker Beechcraft Corporation parts are produced and inspected under rigorous procedures to insure airworthiness and suitability for use in Hawker Beechcraft Corporation airplane applications. Parts purchased from sources other than those approved by Hawker Beechcraft Corporation, even though outwardly identical in appearance, may not have the required tests

Page 16: Mop 306094

Page 2Jul.2009Introduction

HAWKER 125 (SERIES 1 THROUGH 900XP) M&O FOR MINIMUM EQUIPMENTLIST

and inspections performed, may be different in fabrication techniques and materials, and may be dangerous when installed in an airplane.

Salvaged airplane parts, reworked parts obtained from sources not approved by the Hawker Beechcraft Corporation or parts, components or structural assemblies, the service history of which is unknown or cannot be authenticated, may have been subjected to unacceptable stresses or temperatures or have other hidden damage, not discernible through routine visual or usual nondestructive testing techniques. This may render the part, component or structural assembly, even though originally manufactured by the Hawker Beechcraft Corporation, unsuitable and unsafe for airplane use.

Hawker Beechcraft Corporation expressly disclaims any responsibility for malfunctions, failures, damage or injury caused by use of parts not approved by the Hawker Beechcraft Corporation.

WARNING: Any maintenance requiring the disconnection and reconnection of flight control cables, plumbing, electrical connectors or wiring requires identification of each side of the component being disconnected to facilitate correct reassembly. At or prior to disassembly, components should be color coded, tagged or properly identified in a way that it will be obvious how to correctly reconnect the components. After reconnection of any component, remove all identification tags. Check all associated systems for correct function prior to returning the airplane to service.

B. Correspondence

If a question should arise concerning the care of your airplane,it is important to include the airplane serial number in anycorrespondence. The serial number appears on the modeldesignation placard. Refer to Chapter 11 of the IPC for placardlocation.

Stall Warning Identification System

1) (Series 1 through 700, Only)

1. Connect the pressure outlet of one pitot/static test set to the right pitot head, and the pressureoutlet of the other test set to the operative wing stall detector vent.

2. Confirm that No.6 static vent orifices on each static vent plate are clear of obstruction.

3. Energize PE busbar.

4. At the pitot head connection, apply sequentially the pressure (P) values given in Table 2, and ineach case slowly increase pressure (V) to the stall detector vent until the stick shaker motoroperates. Note V pressure at each point.

5. Verify that V pressures meet requirements of Table 2, and then release pressures.

NOTE

Table 2 provides a V/P ratio of 0.71 ± 0.02 on increasing pressure, when checked using Millimeter(s) (mm) water.

NOTE

When A.S.I. gauges (calibrated in knots) are used as alternative to mm water gauge, the readings will not provide the same ratio as mm water to knots as conversion is not linear. Reference Check Pressures Table 2.

6. Remove test set connection from pitot head and apply increasing pressure to stall detector ventuntil stick shaker motor operates. Maintain this vent pressure, reconnect test set to pitot headand apply increasing pressure (P) until warning system cuts out. Verify that, at cutout, thepressure (P) was between 76.5 and 86.0 mm water (70 ± 2 knots). Release pressures.

7. Disconnect and remove test sets.
