The required work must be carried out in accordance with one of the two referenced technical documents: AMD SB BA F10-0095 (F10-34-006) or SGAC AD 75-138-1. (See: Document; Compliance.)\n\n• Which aircraft are affected: The AD applies to all Falcon 10 aircraft that are equipped with Badin Crouzet total pressure probes, part number 33790-10, except those aircraft that already have been modified in accordance with Service Bulletin F100096. (See: Applicability.)\n\n• Timing and enforceability: The directive sets the compliance time as “Forthwith,” meaning the modification must be done without delay. The AD is issued under the Commonwealth Civil Aviation Regulations and is therefore a mandatory regulatory requirement for the listed aircraft. (See: Compliance; header identifying Civil Aviation Safety Authority / Part 39.)\n\n• How it works in practice and who acts: Operators of affected Falcon 10 aircraft must arrange for the modification to be performed by an appropriate maintenance organisation or certificated engineer using the procedures in the referenced documents. The AD itself does not specify technical steps; it delegates the method to the cited service bulletin or foreign AD. (See: Document.)\n\n• Who pays and what changes for them: The text does not allocate funding or state who pays. Mechanically, the financial and operational burden falls on the entities that operate and maintain the affected aircraft, because they must arrange and carry out (or contract) the modification to achieve compliance. The AD does not describe subsidies, reimbursements, or a cost-sharing mechanism. (See: Applicability; Document; Compliance.)\n\n• Enforcement, discretion and information dependencies: The AD leaves no discretionary timing (it requires action “Forthwith”), but it relies on the referenced technical documents to specify the detailed work. This creates a dependency on those external documents for scope of work, parts, and procedures. The AD also requires operators to determine whether their aircraft are already modified to SB F100096 (which exempts them). The directive does not itself describe inspection, verification, or follow-up procedures beyond the compliance instruction. (See: Applicability; Document; Compliance.)\n\n• Official rationale and practical trade-offs: The provided text does not include an explicit statement of the safety problem or rationale for the modification. The AD’s mechanism — mandatory, immediate modification per a service bulletin or an AD — imposes costs (maintenance time, parts, labour, aircraft downtime) and changes operator behaviour (arranging and documenting the modification). It concentrates obligation on the owners/operators of the affected Falcon 10 aircraft and disperses technical execution to maintenance providers. Implementation risk and compliance burden are driven by (a) access to and clarity of the referenced documents, (b) availability of parts and qualified personnel, and (c) the need for operators to verify whether SB F100096 has already been applied to any given aircraft.

Think of it like a compulsory recall notice, but for aircraft parts.\n\n**What it does:** It requires owners and operators of specific **AMD Falcon 10 series aeroplanes** to modify their **total pressure probes** (instruments that measure air pressure to help determine speed and altitude). The affected probes are made by **Badin Crouzet**, part number **33790-10**.\n\n**Who must act:** Anyone operating a Falcon 10 aircraft that:\n- Has **not** already been modified according to **Service Bulletin F100096** (a manufacturer's technical instruction), **and**\n- Is fitted with the specific Badin Crouzet probes mentioned above.\n\n**What must be done:** The aircraft must be modified following one of two approved technical documents:\n1. **AMD Service Bulletin BA F10-0095** (also known as F10-34-006), **or**\n2. **SGAC AD 75-138-1** (a French aviation safety directive, since AMD is a French manufacturer).\n\n**When:** **\"Forthwith\"** — meaning immediately, without delay. This is urgent.\n\n**Why it matters:** Faulty total pressure probes can give incorrect airspeed or altitude readings, which is extremely dangerous during flight.
