3 Intrductin Page 2 Intrductin t the Quarterly Safety Summary Reprt Welcme t the quarterly safety summary reprt fr the spring f 2017 (Oct/Nv/Dec). The purpse f this dcument is t summarise the accidents and serius incidents that ccurred during the spring quarter f There were fur fatalities in this perid and eight serius injuries. The fur fatalities and fur f the serius injuries ccurred in private sprt aircraft accidents. Five f the seven minr injuries in this quarter als ccurred in private sprt aircraft accidents. Many f these accidents ccurred during the landing phase f flight. Five f the six critical incidents in this quarter were Airspace Incidents. Three invlved near miss events between small aerplanes and helicpters, and tw invlved unmanned aircraft (near large aerplanes). There were als a few majr incidents invlving unmanned aircraft, and many cases f cnflicts and reduced separatin between aircraft. Pr safety practices by airprt grund crew were reprted in large aircraft transprt peratins including damage t a prpeller blade frm a glf cart. Agricultural helicpters suffered wire strikes, and agricultural aerplanes (Pacific Aerspace Cresc ) suffered frm jammed cntrls (including elevatr due t cntact with a bush; and ailerns due t a detached wing tip). In the large aerplanes sectr there were reprted landing incidents including buncing and tail strikes. This quarter als saw several freign registered aircraft n private peratins encunter difficulties with Air Traffic Management prcedures int Palmerstn Nrth and Queenstwn. The next six mnthly Aviatin Safety Update will be published befre the 30 th f June Safe flying, J.D. Stantn Manager Intelligence, Safety & Risk Analysis jack.stantn@caa.gvt.nz

4 Executive Summary Page 3 Executive Summary - Aviatin Safety t 31 December 2017 There were 30 accidents in the spring f There were three fatal accidents in this quarter, all in private peratins (there were als three fatal accidents in the spring quarter f 2016): an amateur built aerplane (micrlight) with tw peple n bard; a class 2 micrlight (glider) with ne persn bard; a glider with ne persn n bard; fr details see page 5.

10 Sectin 2 - Incidents Page 9 Sectin 2 - Incidents This sectin describes selected incidents frm the perid. In the perid 1 Octber t 31 December 2017 there were a ttal f 1,636 incidents reprted t the CAA, the 121 incidents presented here have been selected n the basis f significance t risk management. Fr brevity the text may be cndensed frm the riginal ccurrence ntificatin. In sme cases the aircraft mdel descriptins have been reduced t a sectr (e.g. large jet). This is fr tw reasns: t maintain the privacy f the reprter, and t fcus n the nature f the incident. In many incidents such as airspace ccurrences, the specific aircraft type is nt relevant t the prblem. By cmparisn fr defect incidents the specific mdel is highly relevant, but the lcatin is nt. The ccurrences are gruped by sectr t enable cnsideratin f specific risks. While this is intended t assist peratrs t identify their sectr relevant risks, there will be sme events ccurring in a given sectr that culd equally ccur in ther sectrs.

A preceding departure, a twin turbprp, was n a Damb Departure and entered clud at 2,200 ft. The turbine was instructed t enter the circuit at 1,500 ft r belw but crew advised that they preferred the standard missed apprach and climb t 3,000 ft. Essential traffic infrmatin passed t the turbprp crew. When the turbine crew were requested t advise intentins, they advised that aircraft was climbing t 3,000 ft n the standard missed apprach. Aircraft instructed t immediately cntact Wellingtn Terminal Apprach. CAA safety investigatin in prgress. (17/7626) Wellingtn, twin turbprp engine: RPAS encunter in cntrlled airspace. (17/6472)
