Fault rectification after airworthiness reviews - What is changing and what does EASA Part M-Light involve?
As the aviation supervisory authority, the FOCA carries out airworthiness reviews relating to the issue of Airworthiness Review Certificates or ARCs. These are based on the provisions of European Regulation EU No. 1321/2014 (above all M.B.902 and M.A.710).
In the event of complaints about aircraft there are two stages. In the case of Stage 1 defects, the airworthiness of the reviewed aircraft is affected directly. This leads to immediate grounding. The aircraft may be put back into operation only when the defects have been remedied (c.f. also M.A.403(a)). Stage 2 defects, on the other hand, do not directly affect airworthiness. Their remediation could be postponed for a period.
In this respect the EASA wishes to implement Europe-wide harmonisation, which is also logical with regard to the introduction of EASA part M “light”. This involves various easements to General Aviation and will provisionally be introduced in Switzerland in February 2020. Whilst nothing changes in respect of Stage 1 defects, the practice for Stage 2 defects is being adapted.
To date, in the case of Stage 2 defects, though the ARC has been issued, the keeper of the aircraft had to provide the FOCA with evidence of rectification of the defects within a period of two months. Now the ARC will be issued only after remediation, including all Stage 2 defects. However, this does not represent more stringent conditions or even grounding of the aircraft by analogy with Stage 1 defects.
Rather, in the spirit of M.A.403, importance is being attached to defect management and therefore to the responsibility of maintenance personnel or, with the new EASA Part-M “light”, to the correspondingly new privileges of the keeper of the aircraft/pilot. The latter may now assess independently, on the basis of specific criteria and preconditions, when and how the raised complaints or defects or faults on the aircraft are dealt with.
To this end, the operational standards (“Minimum Equipment List”) and the manufacturers' technical instructions (“maintenance data”), if available, are to be consulted. There is therefore the possibility of deferring the remediation of a complaint or a defect or a fault, in extreme cases until the next regular check. In the context of this “defect management”, deferred complaints are to be listed in a “hold item list/HIL”, and in the flight logbook or “Tech Log”, especially if operational consequences result from the complaints and pilots subsequently using the aircraft have to be informed accordingly.
In this context, the review process is deemed to be completed as soon as evidence of remediation of the Stage 2 complaint(s) or the regular deferral of the complaints in accordance with M.A.(L) 403 has been submitted to the FOCA. The aircraft then receives the new ARC.
Since the existing ARC continues to remain valid during the review process (unless Stage 1 defects have been found), it is worthwhile undertaking the review of the aircraft in good time, within the review window of 90 days. Sufficient time therefore remains for the remediation or the deferral of the complaints in order to maintain the new ARC without any interruption.
The evidence for the actual remediation of the complaints (e.g. work report) will no longer be examined within the framework of the regular review process for the issuing of the ARC in the case of deferral according to M.A.(L) 403. The implementation of “defect management”, however, is clearly a subject of the next airworthiness review and may also be reviewed in the event of a focused “ACAM” inspection.
CAMOs too must assure their processes accordingly, including in relation to the recommendations for the issuing of ARCs. This means that they must also have rectified the defects in the above-mentioned sense before the issue of an airworthiness review certificate can be applied for to the FOCA with a recommendation. The same applies by analogy to airworthiness review certifications which are issued directly by the CAMO under the so-called “I privilege”.
All in all, the change in practice involves only a minor adjustment. Taking into account certain requirements, in particular in relation to planning (applicable periods), additional flexibility may even be assumed. This is the case especially in relation to the new privileges which are being introduced by the EASA Part-M "light".
Light Sport Aircraft under EASA Permanent Flight Conditions – What are the steps to to pay attention to when changing the holder/owner
Which aircraft types are affected?
In the Swiss Aircraft Register are currently various aircraft registered which are based on Permanent Flight Conditions introduced by EASA for Light Sport Aircraft (LSA) aircraft which can’t be effectively transited to full Type Certification (TC) after the TC processes has been finished with various companies. The affected types are:
These aircraft types are currently still in the EASA LSA-transition process to full LSA TC (as of August 2018):
What are the steps to follow in case for such an aircraft the change of the operator/owner is needed?
The standard procedures for the modification of operator/owner details can be found on the FOCA website: HERE.
If a change of the operator/owner of a Light Sport Aircraft flying under EASA Permanent Flight Conditions is needed, please fulfill also the following procedure to transferring all the legal responsibilities for each individual (by Serial Number) aircraft design to the new operator/owner. This is tracked using an Aircraft Data Sheet (ADS), which is an integral reference of the approved Flight Conditions (EASA Form 18B).
Therefore, when the operator/owner is changed, the old Flight Conditions (FC) including the ADS became automatically invalid and an operation of such aircraft automatically illegal.
Apply for New Flight Contitions at EASA:
The new owner should send to EASA the application (EASA Form 37) for new Flight Conditions (and therefore for the update of the ADS) on the first day when his ownership was tracked by the Aircraft Register of the National Aviation Authority (NAA).
Adaptation of the aircraft maintenance programme (AMP) template to EASA modifications
The FOCA has adapted and reissued its template for maintenance programmes for aircraft that are subject to the specifications of the EASA. The revised version 4.0 (cf. FOCA collection of forms) incorporates the changes in Commission Regulation (EU) 2015/1088, but has also been combined with existing elements of the two previous versions (3.0 and 3.1). This means that Swiss aircraft operators now have an optimal template at their disposal.
Use of the template is not mandatory, but it offers the advantage that maintenance programmes that are prepared with it will already be suitable for approval in terms of structure and form. The use of this template is intended to simplify the process of preparing aircraft maintenance programmes.
The following templates are available in the FOCA collection of forms: Airworthiness:
Changes in Commission Regulation (EU) 2015/1088
Operators of non-commercial ELA 1 aircraft* can now declare a maintenance programme themselves and no longer have to submit it to the relevant authority for approval. Furthermore, it is now possible to have a maintenance programme approved by a CAMO (continuing airworthiness maintenance organisation) in an indirect procedure. Because aircraft maintenance programmes still have to meet minimum requirements, however, it is clearly beneficial to use the available templates.
* Definition of ELA 1: cf. Article 2(k), Commission Regulation (EU) 1321/2014
Introduction of VHF radio in 8.33 kHz channel spacing
On 16 November 2012, the European Commission issued Implementing Regulation (EU) No. 1079/2012 in which it published the requirements concerning the voice channel spacing for the single European sky. This Regulation describes a Europe-wide uniform and tiered procedure for the introduction of 8.33 kHz channel spacing for VHF aeronautical radio.
For flights operated in accordance with IFR (Instrument Flight Rules) or flights as of a flight level above 195, 8.33 kHz channel spacing was already introduced on a step-by-step basis as of 17 November 2012. With effect from 1 January 2018, 8.33 kHz spacing will be binding for all flights and for all airspaces in which the carriage of a VHF aeronautical radio on board is a legal requirement.
How many 8.33 kHz devices are required?
If the relevant legal provisions call for two independently functioning radios*, it has to be assumed that both devices must be capable of handling 8.33 kHz.
*The applicable regulations can be deduced from the MMEL/Master Minimum Equipment List, MEL/Minimum Equipment List or AFM/Aircraft Flight Manual, or from operational provisions, especially Regulation (EU) No. 965/2012.
What is the situation with respect to old devices?
Old devices with 25 kHz channel spacing do not necessarily have to be removed. As long as a device capable of handling 8.33 kHz spacing is installed (mandatory equipment), old devices may remain in the cockpit as supplementary equipment, even though they cannot be operated in the 8.33 kHz range (e.g. for monitoring). However, they may no longer be used for transmitting, even if the allocated frequency can still be used with 25 kHz channel spacing. The reason for this is that interference with neighbouring frequencies can occur. The sole exception here applies to the international emergency frequency, 121,500 MHz, where there is sufficient separation. The following information must be displayed on radios with 25 kHz channel spacing if they are retained in the cockpit: “VHF-COM transmission on 121,500 MHz only”.
Are there any other requirements that have to be met?
The replacement of a radio represents a modification of an aircraft that requires a permit. Exceptions may apply for certain aircraft categories and preconditions in accordance with CS-STAN*. Furthermore, radios must be approved in accordance with TSO/ETSO /EUROCAE ED-23B (as per ICAO Annex 10). Handheld radios do not comply with these requirements.
Simplified validation of FAA STCs as of 2017
Since 1 January 2017, EASA has offered a simplified procedure in Europe for validating Supplemental Type Certificates (STCs) published by the US civil aviation authorities, the Federal Aviation Administration (FAA). Until such time as the technical implementation procedures (TIP) under the Agreement between the USA and the EU on cooperation in the regulation of civil aviation safety (BASA) have been amended accordingly, the owner of an aircraft or of a Continuing Airworthiness Management Organisation (CAMO) may also apply for validation from EASA. However, only aircraft meeting the following criteria can benefit from the simplified procedure for validating FAA STCs:
Before filing a duly classified "EASA validation of FAA Supplemental Type Certificate classified as Basic and limited to one serial number" with EASA, the EASA Product Certification Manager (PCM) of the aircraft type concerned must be consulted. If the PCM is unknown, the application can be sent by e-mail to: GADadmin@easa.europa.eu. The STC validation is effective only for the serial number of the aircraft concerned.
Agreement between the IAC AR (Russia) and the FOCA concerning maintenance companies
In November 2016 a memorandum of understanding was signed in Bern and Moscow between the Russian Interstate Aviation Committee (IAC AR) and FOCA regarding the surveillance of subcontractors carrying out work for Swiss maintenance organisations. The aim of this agreement is to bring about closer cooperation and the mutual recognition of oversight activities.
EASA Safety Concerns regarding Hellenic Civil Aviation Authority Inspections (HCAA) of Year 2014
In 2014, the European Aviation Safety Agency (EASA) carried out an inspection of the Hellenic Civil Aviation Authority (HCAA). The inspection identified a safety-related non-conformity in connection with alleged examination fraud at the Part-147 maintenance training organization, Hellenic Aviation Training Academy (HATA).
The underlying consideration was that aircraft maintenance certifying staff could obtain a Part-66 license based on Certificates of Recognition issued by HATA. Staff having gained such a Part-66 licence can therefore release aircraft post-maintenance without having the required basic knowledge.
For these reasons, the European Commission determined that Certificates of Recognition issued by HATA after examination of basic knowledge in technical modules could not serve as the basis for the issue of a Part-66 licence. Part-66 licences issued on the basis of such Certificates of Recognition do not constitute sufficient evidence of knowledge and must be re-assessed by the competent authorities (see Commission Decision (EU) 2016/2357).
The revised EASA Safety Information Bulletin (SIB) of 11 January 2017 (available in the EASA Safety Publications Tool) on Commission Decision (EU) No. 2016/2357 establishes inter alia the steps to be taken by maintenance companies and licence holders in this situation. It requires that the privileges granted by the licence be suspended until such time as the authorities issuing the licence have tested the holder’s knowledge.
Holders of Part-66 licences issued on the basis of HATA Certificates of Registration and maintenance organizations knowing of the existence of such Part-66 licences are therefore asked to contact the Federal Office of Civil Aviation (FOCA, Technical Organisations Section (STOB), Mühlestrasse 2, 3063 Ittigen, e-mail: aml@bazl.admin.ch) by 28 February 2017.
Exemptions for multi-engine turbine-powered aircraft with a maximum certified take-off mass (MCTOM) of 5,700 kg
Since 25 August 2016, multi-engine turbine-powered aircraft with a maximum certified take-off mass (MCTOM) of 5,700 kg have been classified as complex motor-powered aircraft (CMPA) under Commission Regulation (EU) 2015/1536.
Contrary to the provisions of Commission Regulation 1321/2014 applicable to CMPA, in Switzerland the non-commercial operations of CMPA are exempted from CAMO and Part-145 maintenance organisation obligations, and from other CMPA-relevant technical provisions.
These exemptions are valid until 1 January 2020.
Implementation of EASA Part-NCO
Change of definition: goodbye "large aircraft", hello "complex aircraft". What it could mean
Commission Regulation (EU) 1536/2015 amending EASA-Part M (Commission Regulation (EU) No 1321/2014)
A new definition has made its appearance in EASA Part-M, thanks to Commission Regulation (EU) 1536/2015. The regulation dates from 16 September 2015, and was expected to come into force in Switzerland on 15 May. However, since the regulation itself stipulates a 25 August 2016 implementation deadline, its implications, as described below, will not come into legal force until that day, at the earliest. Furthermore, the European Commission is expected to deliberate over the next few months on the possibility of a further extension, going beyond 25 August 2016. Aircraft operators who are affected by the change should monitor the EASA website or that of the Swiss Federal Office of Civil Aviation.
The definition of "large aircraft" (aircraft over 5700 kg or multi-engine helicopters), which hitherto has been used to decide whether to apply the stricter maintenance requirements for continuing airworthiness (in particular the CAMO requirement), is to be replaced by a new definition, "complex aircraft", which will serve as the criterion for the stricter demands as from 25 August 2016.
A complex aircraft is one that is
In some cases the new definition will mean that the more demanding requirements may apply to a formerly exempt aircraft, depending on the number of engines and the passenger seating capacity. Thus, an aircraft that, prior to this amendment, fell outside the definition of "large aircraft" because its weight was under 5 700 kg, for example, could now be reclassified as a complex aircraft. (A common example would be a two-engined turboprop aircraft.)
By contrast, for helicopters the change could work in the opposite direction by relaxing the requirements, because the change means that multi-engined helicopters are no longer automatically classified as large aircraft.
Operators of aircraft that are affected by this change are required to make the necessary changes. Operators who now have an obligation for CAMO compliance are requested to send the Federal Office of Civil Aviation a contract with an approved CAMO (unless they have an in-house CAMO) in a timely fashion. (The contract should be sent to the Airworthiness Section, "Sektion Lufttüchtigkeit Flugmaterial Zürich".) The anticipated deadline is 25 August 2016.
Change to the practice of approval for standard changes to Annex II aircraft
Annex IV to Decision 2015/016/R Certification Specifications for Standard Changes and Standard Repairs (CS-STAN)
On 8 July 2015 EASA issued acceptable methods and techniques for identifying and performing standard changes and repairs on aircraft (on the basis of Regulation (EU) No. 748/2012, or EASA Part-21). That meant that all eligible changes and repairs covered by CS-STAN can be carried out and certified without formal EASA approval.
In future, the Federal Office of Civil Aviation will accept changes to Annex II aircraft (which are not covered by EASA's "Basic Regulation") if they were carried out in compliance with CS-STAN and certified with FOCA form 123.
New option for Airworthiness Review of ELA 1 aircraft
New option for conducting airworthiness reviews of ELA 1 aircraft
Under the new Commission Regulation (EU) 2015/1088, Part 145 or Part M Subpart G maintenance organizations will be authorized to conduct airworthiness reviews of ELA1 aircraft not involved in commercial operations and issue an airworthiness review certificate (ARC 15c). To do this they require FOCA authorization. Commission Regulation (EU) 2015/1088 was expected to enter into force on 15 May 2016.
Agreement with FAA on Implementation Procedures for Airworthiness (IPA)
Negotiations over several years have led to the conclusion of an agreement between the Swiss Federal Office of Civil Aviation and the United States Federal Aviation Administration regarding reciprocal acceptance of aircraft, aircraft engines, propellers, aircraft components and other equipment. In particular, the agreement will make it possible to export modifications to aircraft types (validation of supplemental type certificates), putting Swiss companies in a stronger position in a domain where they were hitherto at a disadvantage, compared with competitors in the European Union. The agreement can be viewed here.
