TYPE CERTIFICATE DATA SHEET NO. A3EU 
 
This Data Sheet, which is part of Type Certificate No. A3EU prescribes co nditions and limitations under which the product for 
which the Type Certificate was issued meets the airworthiness requirements of the Federal Aviation Regulations. 
 
Type Certificate Holder:   Textron Aviation Inc. 
     One Cessna Boulevard 
     Wichita, Kansas 67215 
 
Type Certificate Holder Record:  Raytheon Aircraft Company transferred to 
     Hawker Beechcraft Corporation on March 26, 2007 
 
     Hawker Beechcraft Corporation transferred to  
     Beechcraft Corporation on April 12, 2013. 
 
     Beechcraft Corporation transferred to  
     Textron Aviation Inc. on October 12, 2016. 
 
Type Certificate A3EU was transferred from Raytheon Corporate Jets Inc., 3 Bishop Square, St. Albans Road West, Hatfield, 
Hertfordshire AL 10 9NE, United Kingdom, to  Raytheon Aircraft Company (RAC) on August 1, 1995.  Coincident with this 
transfer, the Federal Aviation Administration (FAA) has accepted the status of State of Design and State of Manufacture as defined

A3EU 
 Rev. 44 
Page 2 of

by Annex 8 to the Convention on International Civil Aviation.  Prior to August 1, 1995, products identified under Type Certificate 
A3EU were approved by the FAA in accordance with the Federal Aviation Regulation appropriate to Imported Products (FAR 
21.29).  Effective August 1, 1995 and after, these products are to be considered domestic products for the purpose of certification, 
and Federal Aviation Regulation 21.21 becomes appropriate. 
 
Effective May 28, 1999, certain models identified as “B” series that had been previously certified by the UK Civil Aviation 
Authority were added to Type Certificate A3EU and this Data Sheet.  The process for type certification of these aircraft is 
considered analogous to issuance of export airworthiness approvals, with exceptions, as allowed under 14 CFR 21.325(c).   
Under that section the requirements that are not met and the differences in configuration, if any, between the product to be exported 
and the related type certificated product, are listed on the export airworthiness approval as exceptions.  The UK certificate d “B” 
series aircraft can be considered to be the US approved type certificated “A” series with exceptions.  The UK approved “B” series 
are eligible to receive FAA airworthiness certificates and registration for operation in the United States as a US approved “B” series 
when modified to comply with US standards (i.e. the modification eliminates the exception; see NOTE 50) and when all 
Airworthiness Directives applicable to the equivalent “A” series have been incorporated.   
 
The box in the upper right corner of page 1 ident ifies the FAA Approved Series and Models.  The FAA has accepted the 
responsibility for the promulgation to International Civil Aviation Organization (ICAO) Contracting States of airworthiness 
information for all such products in accordance with Annex 8.  T he Type Certificate Holder designated in this data sheet holds 
Type Design authority for the production of data associated with all such products.

Hawker Siddeley Model HS.125 Series 700B (Transport Aircraft), Approved May 28, 1999. (See NOTE 56) 
 The HS.125 Series 700A and HS.125 Series 700B aircraft differs respectively from the BH/HS.125 Series 600A and the 
HS.125 Series 600B aircraft in the following major respects:  (i) Garrett AiResearch TFE 731-3 engines replace the Rolls 
Royce Viper 601-22 engines,  (ii) Modifications to associated aircraft systems consequential to the engine change,  (iii) 
Minor changes to improve aerodynamic efficiency and aircraft appearance,  (iv) Provisions for a New Automatic Flight 
Control System - Collins FCS.80,  (v) Addition of a single point pressure refuel/defuel system,  (vi) Reduction in certificated 
taxiing and take-off (brake release) weights,  (vii) Reduction of MMO from 0.78 (Post Modification 252320 Part A) to 0.77.

XXI. Hawker 750 (Transport Aircraft) Approved February 08, 2008 (See NOTES 1, 2, 3, 8, 63, 64 & 70). 
 The Hawker 750 differs respectively from the Hawker 800XP, which retains the certification basis and is similar in 
configuration with the following exceptions:  
 
a) External Baggage Unit:  The Hawker 750 incorporates as standard equipment, an external baggage unit in place of 
the aft ventral fuel tank installed on the Hawker 800XP.  The standard configuration of the Hawker 750 uses the 
previously certified external baggage unit with improvements.  This baggage unit meets the requirements of 14 CFR 
25.857(d)(1)(2)(3)(5) as Amended through 25-32 for Class D baggage compartments.  
 
b) MTOW:  The range and MTOW of the Hawker 750 is less than that of the Hawker 800XP as a result of the decrease 
in available fuel.  Changes to the weight and center of gravity envelope reflect the alternative loading capabilities 
provided with the external baggage unit. 
 
c) Avionics:  Hawker 750 Pro Line 21 avionics installation is revised to include a single FMS-6000/Single GPS in lieu 
of a dual installation. 
 
d) Introduction of Hawker 750 designation.

NOTE 1.   (a)  A current weight and balance report, including list of equipment in certificated empty weight 
   and loading instructions, must be provided for each aircraft at the time of original certification. 
   (b)  The airplane must be loaded so that the C.G. is within the specified limits at all times with 
   the effect of fuel use and movement of crew and passengers from their assigned positions being 
   considered. 
   (c)  The "drainable unusable fuel" is the amount of fuel in the tanks which is unavailable to the 
   engines under critical flight conditions as defined in CAR 4b.416.  This drainable unusable fuel 
   does not include the "tank trapped fuel".  The total unusable fuel must be included in the airplane 
   empty weight or be suitably accounted for in the airplane weight and balance report.  The total 
   volume of unusable fuel in gallons is as follows:

NOTE 50. Some aircraft delivered new from the UK to international customers may not necessarily comply in full  
with the defined certification basis on which this TC has been granted due to overriding Foreign Authority 
requirements which have been satisfied for aircraft delivered into their country. 
 There are two basic certification standards for the DH/HS/BH/BAe.125/Hawker series of airplanes.  One  
is the US FAA Type Certificate standard.  Aircraft certified to this standard are identified with an “A” in the 
Model suffix.  The other certification standard is based on requirements established by the UK Civil Aviation 
Authority (CAA).  Aircraft certified to the UK CAA standards are identified as “B” versions and include the 
following Models, Series: 1B, 1B-522, 1B/S-522, 1B/R-522, 3B, 3B/R, 3B/RA, 3B/RB, 3B/RC, F3B, F3B/RA, 
400B, 400B/1, 401B, 403A(C), 403B, F400B, F403B, 600B, 600B/1, 600B/2, 600B/3, F600B, 700B, 800B, and 
1000B.  The ‘B’ models are equivalent to the ‘A’ models and meet U.S. certification requirements with the 
exception of the overriding UK CAA requirements and customer requested optional modifications approved by 
the UK CAA.  While most countries outside of the UK and U.S. accept either “A”, “B”, or both versions of the 
aircraft, modifications of these aircraft are sometimes required to satisfy national variations in the certification 
standards established by the importing countries.  Due to the wide range of potential configurations, specific 
instructions for modifying an airplane from one country standard to another are not available in a pre-published 
format.  In those cases, where it does become necessary to convert an aircraft from one certification standard to 
another, or to show the equivalency to the U. S. standard, the document used will be a serial number specific 
Service Bulletin issued by the Type Certificate Holder.  This Service Bulletin will be FAA Approved. 
 
NOTE 51. Raytheon Aircraft Company Service Bulletin No. 00-11 titled "General-Record of UK Airworthiness Directives 
(AD) at the Time of Transfer of ICAO Annex 8 Responsibilities from UK CAA to US FAA" will be used to 
document the AD’s issued by the UK CAA prior to August 1, 1995.
