Ikarus C42 Service Bulletin for all models

High hours examples of C42 aircraft have exhibited cracks emanating from the corners of the cut-outs in the main fuselage tube where the nose undercarriage leg and the A-strut are attached. The problem appears primarily to affect high hours early examples of the C42 on which the affected cut outs were made manually. Later models have machined cut-outs which are thought less likely to exhibit the cracking problem. More recently the A-strut attachment has been re-designed and there are no cut-outs for this item in the fuselage tube. At least for the initial issue of the service bulletin, all C42 aircraft must be inspected regardless of the build standard and manufacturing standard of the fuselage tube. If such cracks were allowed to propagate, the structural integrity of the nose undercarriage leg, A-strut and engine mountings may be compromised.

Compliance is required as follows, unless previously accomplished:

  1. For aircraft with over 2000 hours of operation, carry out the inspection in paragraph 5 of this MPD before further flight.
  2. For aircraft with over 1000 hours of operation, carry out the inspection in paragraph 5 of this MPD at the next annual inspection or the next 100 hour inspection, whichever occurs first.
  3. Repeat the inspection carried out under paragraph 1 or paragraph 2 of this MPD at 500 hour intervals.
  4. If the main fuselage tube has been replaced in an aircraft, the requirements in paragraphs 1, 2 and 3 of this MPD are applicable from the time of installation.
  5. Visually inspect the main fuselage tube, inside and outside surfaces, in the vicinity of the nose undercarriage leg and Astrut (if applicable) attachment cut-outs for cracking. See example photographs in the referenced Owner’s Service Bulletin. To facilitate the inspection the upper and lower cowlings must be removed as well as the sound deadening foam on the cockpit side of the firewall. If there is doubt whether there is cracking, dye penetrant crack detection may be used in addition to the visual inspection.
  6. The aircraft owner may carry out the inspection in paragraph 4, if they consider themselves capable. Alternatively, a BMAA or LAA inspector may carry out the inspection.
  7. If any cracks are found, ground the aircraft then inform Red Aviation and obtain and implement a repair scheme before further flight.

Transponder Notice

Can all our Members using Mode S Transponders make sure that the transponder is operating with the correct code. When a new transponder is purchased it must be coded with a code received from the IAA Registration Department. If you have (or are going to purchase) an aircraft from outside Ireland with a Mode S transponder, you must inform the IAA and then MUST change the transponder code before the aircraft can fly.
In relation to getting the code changed ,you can ask the Tech office for information in relation to this (

IAA Publish Further Guidance on using Petrol in Aircraft

Further to the NMAI’s advice last week that members should be careful about where they source their fuel, the IAA have now published Safety Leaflet IGA9. We urge all members to carefully read the attached guidance. Stretched fuel will cause damage to your engine and can lead to in flight engine failure. Be aware of cheap fuel and try to source fuel from a reputable filling station with a high turnover of petrol. If you suspect that the fuel you have used in your engine may not have been up to standard please contact the NMAI Tech Office for further guidance.

Using Unleaded Petrol (Mogas) in Aircraft

Fuel Quality

The NMAI has been made aware of a number of incidents where sub standard fuel is being sold at filling stations throughout the country. This has caused some serious damage to engines and obviously the potential consequences are fatal.

As a result the NMAI are strongly recommending to our members that they buy their fuel from reputable fillings stations with a high turnover of petrol. It may mean a slightly longer journey for fuel or paying a few extra cents per litre but this could be a small price to pay.

Guidance on use of petrol in microlight aircraft is contained in IAA Airworthiness Notice A16B which is available here:

If you have any concerns or would like to discuss issues relating to petrol quality please feel free to contact the Tech Office


New Tech Office opened at Limetree

At the recent AGM, the NMAI officially opened the new Tech Office at Limetree Airfield. The tech office houses the documentation of all the aircraft that are operated under the NMAI airworthiness scheme (117 aircraft at the last count!), and is the location where all of the permit applications are processed. Since the formation of the NMAI many moons ago, the tech office has usually been located in the home of the Chief Technical Officer. The opening of the office in Limetree marks the first permanent address of the NMAI and is a huge leap forward for the Association. The new office has plenty of space and now holds all of the IT equipment and records required to operate our airworthiness system.

The aircraft documents library


As announced at our recent AGM, Mark Brereton will be taking over from Padraig Higgins as Chief Technical Officer in the next few weeks.


There are plenty of benefits to the association in having a public office. For owners, if you get your aircraft inspected before the expiry of your existing permit, you can fly into Limetree to collect your documentation. We plan on purchasing some tools that inspectors can borrow from the office when carrying out inspections on members’ aircraft. When aircraft have transitioned to 3 years permits, the validity certificates can be signed on the spot at Limetree by the CTO, which will extend the permits validity for another year. The office can also be used as a means to promote the association and grow our membership. If you’re flying in to Limetree, feel free to drop in and say hello!


All future correspondence for the Tech Office including permit applications should be addressed to: NMAI Tech Office, Limetree Airfield, Portarlington, Co. Laois. The new Tech Office email address is

A guide for UK Registered Aircraft & Pilots Visiting Ireland

The NMAI has worked closely with The Irish Aviation Authority (IAA) to make it easier for UK registered aircraft and pilots to visit Ireland.  As a result of those talks the IAA has recently introduced new rules which  make it easier for UK licensed recreational pilots to visit Ireland on short visits. Since 25 May 2012 Ireland is accepting the use of a UK issued NPPL with a Simple Single Engine Aeroplane (SSEA), Self Launching Motor Glider (SLMG), or Microlight Class Rating for use in Ireland which meet the following criteria;

  • The licence holder is not a resident of Ireland; (Proof of residency such as a valid passport. UK DVLA drivers licence or National Insurance Certificate must be provided to the Irish Aviation Authority upon demand.)
  • The licence and ratings are valid for use in the UK;
  • The pilot holds the appropriate medical certification for the licence held;
  • The pilot has at least 50 hours experience in flying aircraft covered by the licence; (evidence of which must be provided to the Irish Aviation Authority upon demand or within 10 working days of being requested.)
  • The pilot is restricted to operation in Class G airspace unless in possession of a valid radio telephony rating and an English Language Proficiency of 4 or higher endorsed on the licence;
  • The licence shall not be used for the purposes of commercial air transport, commercial operations or aerial work. Additional privileges of the licence such as flight instruction, testing or display authorisation may not be used.
  • The licence is restricted to operation only in accordance with daytime Visual Flight Rules.
  • Any conditions, limitations and restrictions applicable on the licence which exceed those listed here shall also be observed.
  • The pilot shall have all required documents available for inspection when operating in the Republic of Ireland including suitable photographic identification document
  • The pilot is familiar with, and adheres to, the requirements detailed in Irish Air Law. See GAM 05-10 for details on the potential differences.
  • The pilot shall report any aviation related accident or serious incident to the Air Accident Investigation Unit (contact details can be found at and also to the Air Accident Investigation Body of both the State of Issue of the licence holder and the State of Registry of the aircraft.

The UK registered aircraft is allowed to stay in Ireland for a period of no greater than 28 days per visit. So you can fly in once a week if you like as long as each stay doesn’t last longer than 28 days. So what if i want to stay for longer than 28 days? Well then you will have to get permission from the Irish Aviation Authority. Please send a brief outline of your proposed visit to and they will advise you.

Microlight Incident Reporting

Following on from the regional Safety Council meetings that the IAA and NACI are running throughout the country, the NMAI have setpu up an incident reporting system in order to report all incidents and mishaps as they happen. This will be 100% CONFIDENTIAL system, your details will not be passed on. We need you to report “everything”, from a broken stub axle, to a de-laminated prop, to a more severe bump…. to the smallest issue…. please submit a report, the info will be put to good use and NO ONE will suffer any consequences for submitting ANY report. All reports go to directly to the NMAI and never directly to anyone else, no paper trail or electronic trace will exist on any report submitted. The main NMAI website will be updated to add this page over the weekend.
