AERODROME TRAINING COURSE – MODULE 7Inspection, Maintenance, Works, Management, Safety and Reporting

LEARNING OUTCOME

Participants will gain an overview of the following requirements and issues concerning:

Aerodrome inspections Conducting works and maintenance when the airport is still

operational Safety management and quality assurance systems and

procedures CAA incident and accident reporting

With access to reference documents they will be able to specify:

detailed zones and work activities permitted on the runway strip

Steps for conducting safety assessment Reporting requirements of aerodrome incidents to CAA

AERODROME INSPECTIONS Inspection Programme – primary responsibility of

Aerodrome certificate holder to ensure the correct functioning or condition of following:

• Pavement areas• Safety and obstacle free areas• Markings and signs• Aircraft loading/unloading and refuelling• Navigation aids• Public protection• Wildlife and airside fencing

Responsibility 3rd Parties – Other organisations such as air navigation service providers may own navigation aids on airside. Ultimate responsibility for visual aids (lighting and marking) rests with the airport certificate holder.

AERODROME INSPECTIONS Inspection Frequency – following considerations:

number of aircraft movements, types of aircraft and operation (VFR/IFR), meteorological conditions, day or night, aerodrome environment, complexity and size of aerodrome, and analysis of results/trends of inspections.

Recording and Reporting – essential good records are kept and prompt reporting to ATC/NOTAM for operational impact and maintenance for fault rectification.

Competency/Equipment of Inspector – important that inspector understands function and operational impact of items being inspected and supported by detailed procedures (SOP) and necessary equipment and support (radio equipped vehicles, management/technical escalation)

AERODROME MAINTENANCE Fault Rectification – reported by inspection programme,

pilots, ATC or routine maintenance inspections. Urgency dependent on operational impact and allowable outages etc

Preventative – routine maintenance to minimise faults and ensure safety (availability, continuity and integrity) of service or facility.

Projects – CAPEX major works to enhance and upgrade current facilities

Access – close proximity to and on runway difficult

Records – essential to keep good records to enable trend analysis etc

RUNWAY WORK ZONES

NOTAM and ATS advice to pilots, consideration meteorological conditionsZone 1 Calibration personnel equipment only when essential other personnel to edge zone 2 for turbojet and edge zone 1 for turboprop light GA aircraftZone 2 all equipment personnel clear for turbojet, okay for otherZone 3 consideration navaid protection zones for personnel/equipment/vehicles and LVO

METHOD OF WORKS PLAN For all major works a Method Off Works Plan (MWOP) is

required:

Management – early appointment of project manager to manage the pre works planning

Consultation - airline and other operators, ATS, works contractor, Airways technical for impact on their facilities,

CAA - does the work require specific regulatory approval –• structures mast penetrating OLS require notification• Is work covered by existing AOC/Exposition

AIS – Use AIP Supplement with use of NOTAM only for notifying start dates. Consider end of project permanent changes required to AIP/Aeronautical charts.

MOWP - AIS

QUALITY MANAGEMENT SYSTEMS – NZ EXAMPLE Swedavia-McGregor Report 1988 recommended fundamental

change to the civil aviation system. CAA up to then provided external QA function through process of constant inspection of the end product and intervention. Change to responsibility be placed on certificated organisations to have QMS with appropriate internal QA procedures.

More effective for CAA to examine systems that control the activities and ensure appropriate procedures in place to address and achieve the required safety standard.

QMS is the structure, responsibilities, processes and procedures of an organisation that promotes and establishes an environment and culture of continuing improvement that will enhance safety.

QUALITY ASSURANCE NZ EXPERIENCE Internal Quality Assurance procedures required to:• Identify, Document and Correct Instances of non-

conformance or non-compliance

139.75 Aerodrome internal quality assurance (a) Each applicant for the grant of an aerodrome operating

certificate shall establish internal quality assurance procedures to ensure compliance with, and the adequacy of, the procedures, plans, systems and programmes, required by Subparts B, C, and D.

(b) The senior person who has the responsibility for internal quality assurance shall have direct access to the Chief Executive on matters affecting the safety of aircraft operations and the performance of the aerodrome services and facilities.

SAFETY MANAGEMENT SYSTEMS

ICAO Annex 14: 1.5.3 States shall require, as part of their safety programme,

that a certified aerodrome operator implements a safety management system acceptable to the State that, as a minimum:a) identifies safety hazards;b) ensures that remedial action necessary to maintain an acceptable level of safety is implemented;c) provides for continuous monitoring and regular assessment of the safety level achieved; andd) aims to make continuous improvement to the overall level of safety.

1.5.4 A safety management system shall clearly define lines of safety accountability throughout a certified aerodrome operator, including a direct accountability for safety on the part of senior management.

SAFETY MANAGEMENT SYSTEMS

Safety is the state in which the risk to harm to persons or of property damage is reduced to, and maintained at or below, an acceptable level through a continuing process of hazard identification and risk management.

A Safety Management System is an organised approach to managing safety, including the necessary organisational structures, accountabilities, policies and procedures.

Concept of Risk is two-dimensional involving both likelihood of occurrence of a hazard and the severity of its potential consequences.

ACCEPTABLE LEVEL OF SAFETY Expressed by 2 measures/metrics – safety performance indicators

and safety performance targets and implemented through various safety requirements

Safety performance indicators – measure of safety performance of an organisation. Must be easy to measure and linked to States (CAA) Safety programme.

Safety performance targets – determined by considering what is desirable and realistic. Should be measurable and acceptable to stakeholders and consistent with States safety programme.

Safety requirements – to achieve safety performance indicators and targets.

Example – no more than one runway incursion per 40,000 aircraft movements (safety indicator); with a 40% reduction in a 12 month period (safety target); the establishment of low visibility taxi procedures (safety requirement).

AERONAUTICAL STUDY - EXAMPLE

1. Scenario - The close proximity of the planned extension of the wind turbine farm to X International Airport and that the proposed turbines will infringe the inner horizontal and conical OLS requires the CAA to conduct an aeronautical study as detailed in CA Rules. The aeronautical study is to identify any risks to airport and aircraft operations and to recommend if required the necessary control measures and mitigations to ensure safe and regulatory compliant operations.

System Description X International Airport is a designated international airport for the State. The airport operator is X. X is a government owned company operating all the airports in the State and the sole provider of air traffic and air navigation services.

The airport is operational 24 hours per day, seven days per week (H24), and has direct schedule international flights to/from Europe, Africa and North America. It also has frequent domestic flights to the other airports in the state. The airport is capable of handling aircraft up to ICAO Annex 14 Code 4D with the current largest aircraft regularly operating at the airport being the Boeing 757-200.

ACCIDENT/INCIDENT REPORTINGAccident means an occurrence that is associated with the operation of anaircraft and takes place between the time any person boards the aircraftwith the intention of flight and such time as all such persons havedisembarked and the engine or any propellers or rotors come to rest,being an occurrence in which—(1) a person is fatally or seriously injured as a result of—(i) being in the aircraft; or(ii) direct contact with any part of the aircraft, including any part that has

become detached from the aircraft; or(iii) direct exposure to jet blast— (2) the aircraft sustains damage or structural failure that—(i) adversely affects the structural strength, performance, orflight characteristics of the aircraft; and(ii) would normally require major repair or replacement of the affected

component— except engine failure or damage that is limited to the engine, its cowlings, or accessories, or damage limited to propellers, wing tips, rotors, antennas, tyres, brakes, fairings, small dents, or puncture holes in the aircraft skin;

INCIDENT Incident means any occurrence, other than an accident, that is associated with

the operation of an aircraft and affects or could affect the safety of operation: Aircraft incident means any incident, not otherwise classified, associated with

the operation of an aircraft: Aerodrome incident means an incident involving an aircraft operation and— an obstruction either on the aerodrome operational area or protruding into the

aerodrome obstacle limitation surfaces; or(2) a defective visual aid; or (3) a defective surface of a manoeuvring area; or (4) any other defective aerodrome facility: Airspace incident means an incident involving deviation from, or

shortcomings of, the procedures or rules for— (1) avoiding a collision between aircraft; or (2) avoiding a collision between aircraft and other obstacles when an aircraft is

being provided with an Air Traffic Service: Bird incident means an incident where— (1) there is a collision between an aircraft and one or more birds; or (2) when one or more birds pass sufficiently close to an aircraft in flight to cause

alarm to the pilot:

CAA NOTIFICATION – NZ EXPERIENCE12.55 Notification of incident A holder of a certificate issued in accordance with the following Parts

must notify the Authority as soon as practicable of any associated incident if the certificate holder is involved in the incident and the incident is a serious incident or is an immediate hazard to the safety of an aircraft operation:

(6) Part 139 ─ aerodrome incident:(d) The notification of an incident required by paragraphs (a), (b), and

(c) must be conveyed by a means acceptable to the Authority and contain, where ascertainable, information in accordance with the following:
