'''Cessna 172 Skyhawk''' - '''C172''' je štirisedežno enomotorno [[Batni motor|batno]] [[športno letalo]], ki ga proizvaja ameriško podjetje [[Cessna]].<ref name="SkyhawkOverview">[http://www.cessna.com/single-engine/skyhawk?trk=NavSingle "Cessna Skyhawk"] {{Webarchive|url=https://web.archive.org/web/20130404235254/http://www.cessna.com/single-engine/skyhawk?trk=NavSingle|date=2013-04-04}} (2013), [[Cessna Aircraft Company]]. Retrieved 2013-04-12.</ref> S ceno 600.000 [[Evro|eur]] predstavlja vstopni model na trg letal splošne kategorije. Prvič je poletela leta 1955 in je po [[Seznam najbolj proizvajanih zrakoplovov|številu najbolj proizvajano letalo]] na svetu z več kot 44 000 izdelanimi, največ 7436 letal v varianti 172M v letih 1973 do 1976. Konkurenti C-172 so: Beechcraft Musketeer, Grumman AA-5 series, Partenavia Oscar (vsi izven proizvodnje), [[Cirrus SR20|Cirus SR20]], [[Piper PA-28 Cherokee]], [[Diamond DA40]] in Vulcanair V1.0. Večina ljudi, ki se šola na C172 in si kupi svoje lastniško letalo raje poseže po hitrejših letalih: [[Beechcraft Bonanza]], [[Cessna 182|Cessna Skylane]], [[Cessna 210|Cessna Centurion]], [[Rockwell Commander 112|Commander 114]], [[Cirrus SR22]], [[Grob G 120|Grob G120]], [[Mooney M20]], [[SIAI-Marchetti SF.260]], [[Piper PA-24 Comanche|Piper Comanche]], [[Piper PA-46|Piper Malibu]], [[Piper PA-32|Piper Saratoga]].

Cessna 172 je načrtovana na podlagi predhodnice [[Cessna 170]]. Leta 1950 je Cessna testirala varianto Cessna 170C z motorjem Continental O-300-A. Potem je spremenila pristajalno podvozje iz repnega v tricikel in certificirala letalo kot Model C172.<ref name="3A12">{{navedi splet|url = http://rgl.faa.gov/Regulatory_and_Guidance_Library/rgMakeModel.nsf/0/263a36336effbcd38625738a004bbe52/$FILE/3A12.pdf|format = PDF|title = Cessna 172 Type Certificate Data Sheet|accessdate = 2010-02-21|last = [[Federal Aviation Administration]]|authorlink = |date = February 2006|archive-date = 2010-10-11|archive-url = https://web.archive.org/web/20101011035525/http://rgl.faa.gov/Regulatory_and_Guidance_Library/rgMakeModel.nsf/0/263a36336effbcd38625738a004bbe52/$FILE/3A12.pdf|url-status = dead}}</ref><ref name="A799">{{navedi splet|url = http://www.airweb.faa.gov/Regulatory_and_Guidance_Library/rgMakeModel.nsf/0/51dcd703defaa00486257243006811e2/$FILE/A-799.pdf|format=PDF|title = Cessna 170 Type Certificate Data Sheet|accessdate = 2010-02-21|last = [[Federal Aviation Administration]]|authorlink = |date=November 2004}}</ref> C172 je hitro postala uspeh, leta 1956 v prvem letu so zgradili več kot 1400 letal. Zgodnje verzije C172 so bile podobne [[Cessna 170|C170]]. Poznejše verzije so imel nagnjeni vertikalni rep, ki je še vedno v uporabi danes. V 1960ih so dodali repno okno "omni-vision". Prva od verzij, ki se podobno obnaša in je podobna današnji verziji je C172M iz 1970ih, od takrat naprej se osnovna struktura ni bistveno spreminjala, so se pa spreminjale verzije motorjev in [[avionika]]. Proizvodnja 172P se je leta 1986  zaustavila in se je ponovno vzpostavila šele leta 1996 z verzijo Cessna 172R Skyhawk (160 KM) in leta 1998  z verzijo Cessna 172S Skyhawk (180 KM). Leta 2005 so se nehali proizvajati urični cockpiti t.i. NAV II in od takrat je v proizvodnji samo še [[stekleni kokpit]] - Garmin G1000 NAV III. Cessno C172R so prenehali proizvajati leta 2008, od takrat je v proizvodnji samo C172SP NAV III. 

Cessne 172 je možno modernizirati s t. i. STC-ji. Lahko se namesti močnejši motor do 210KM, doda se propeler s konstantnimi vrtljaji, v nekaterih primerih je dovoljena uporablja cenejšega avtomobilskega goriva, namesto Avgasa. Druge modifikacije imajo povečano kapaciteto goriva in STOL kit za boljše sposobnosti.<ref>[http://www.aopa.org/pilot/btn172/btn9407.html] ''AOPA Pilot'', May/July 1994</ref> 
Cessne 172 M,N,P se veliko uporabljajo za panoramske polete in tudi za šolanje pilotov, vendar so precej manj ekonomične od dvosedežnih [[Cessna 152|Cessen 152]] in so nagnjene k pristanku na nosno kolo t.i. hard landingu pri učencih, česar posledica je zvita požarna stena, C152 zaradi robustnejše konstrukcije nima teh težav. Cessna 172 R in S imata veliko boljšo zvočno izolacijo in nov izboljšani prezračevalni sistem. Zaradi preproste robustne zasnove združene z moderno avioniko in solidnim injektorskim motorjem C172SP ostaja sodobno letalo primerno za ljudske množice, saj od novih letal na trgu odpušča največ napak.

[[File:Timm-Cook Cessna 172 LV NV.jpg|thumb|Cessna 172 iz leta 1958]]
Leta 1958 je Cessna 172 postavila rekord v najdaljšem letu, ki še vedno stoji danes. 4. decembra 1958 sta Robert Timm in John Cook poletel z letališča Las Vegas McCarran in pristala: 64 dni, 22 ur in 19 minut pozneje na istem letališču. Z letom so nabirali sredstva za Damon Runyon Cancer Fund. Hrano, pijačo, gorivo in olje so dostavljali na letalo s pomočjo tovornjaka, ki je vozil pri isti hitrosti kot so oni leteli. Maratonski let so potem prekinili. S časom 1558 ur se je moč motorja zelo zmanjšala.<ref>{{Navedi splet |url=http://www.trivia-library.com/c/time-and-history-353-pm-longest-air-flight-in-history-begins.htm |title=Time and History 3:53 P.M.
