Airworthiness directives
13 FAA ADs name the Siddeley HS.125 Series 700A
- AD 2009-08-04 We are issuing this AD to prevent smoke and fumes in the cockpit in the event that a blower motor seizes and overheats due to excessive current draw.
- AD 2006-16-18 We are issuing this AD to prevent a bearing error, which could lead to an airplane departing from its scheduled flight path, which could result in a reduction in separation from, and a possible collision with, other aircraft or terrain.
- AD 2006-12-20 We are issuing this AD to prevent loss of all primary electrical power, which could result in the airplane operating only under emergency power.
- AD 2006-01-04 We are issuing this AD to prevent heat and fire damage to equipment adjacent to the fan venturi, which could result in smoke in the cabin and/or burning equipment.
FAQ
Siddeley HS.125 Series 700A questions
How much does a Siddeley HS.125 Series 700A cost?
Radar's rough range is about $750K to $1.7M for a 1982 and $750K to $1.7M for a 1977. From Radar's listing-based estimates for business jets of similar engine thrust and age. These are rough ranges, not appraisals: hours, engines, damage history, equipment and the logbooks move the price of any one aircraft.
What affects the price of a Siddeley HS.125 Series 700A?
What moves the price of any one Siddeley HS.125 Series 700A: total time and engine time, engine program enrollment, damage history, avionics and equipment, and complete logbooks. Build year sets the baseline shown on this page; a Siddeley HS.125 Series 700A with high hours, an engine near overhaul or gaps in its records sells below it, and one with low time, recent inspections and full records above it.
What are the Siddeley HS.125 Series 700A's specs?
As published: up to 15 passengers, a range of 2,330 nm (2,681 statute miles), a high-speed cruise of 424 ktas (488 mph), a ceiling of 41,000 ft and 2 × GARRETT / Honeywell TFE731 series (e.g., TFE731-3R-1H) engines. A given aircraft varies with its completion, weight and modifications.
How far can a Siddeley HS.125 Series 700A fly?
The Siddeley HS.125 Series 700A's published range is 2,330 nautical miles (2,681 statute miles). Winds, payload, cruise speed and the reserves a flight carries change what a given trip can do.
Can a Siddeley HS.125 Series 700A cross the Atlantic?
Not nonstop between New York and London: that is about 2,986 nm, against a published range of 2,330 nm. Aircraft with less range than the crossing make it in legs, with fuel stops in Canada, Greenland and Iceland.
Can a Siddeley HS.125 Series 700A fly to Hawaii?
Only just. Los Angeles to Honolulu is about 2,217 nm with no alternate airport on the way, close to the Siddeley HS.125 Series 700A's published range of 2,330 nm, so winds and load decide whether a given flight can go nonstop.
How fast is the Siddeley HS.125 Series 700A?
The Siddeley HS.125 Series 700A cruises at up to 424 knots true airspeed (about 488 mph), and its maximum operating Mach number is 0.72, as published.
How high can a Siddeley HS.125 Series 700A fly?
The Siddeley HS.125 Series 700A is certified to 41,000 feet. Heavy aircraft climb there in steps as they burn fuel.
How many passengers does a Siddeley HS.125 Series 700A seat?
Up to 15 passengers, the most the type is published for. Many aircraft are completed with fewer, larger seats, so a given Siddeley HS.125 Series 700A may seat fewer.
